Fig. 3 is a perspective view of the developing cartridge 1. Fig. 3 shows a state in which a part of the developing cartridge 1 is disassembled. As shown in fig. 3, the developing cartridge 1 has a casing 11, an agitator 20, a developing roller 30, a gear portion 40, and an IC chip assembly 50.
The housing 11 is a casing capable of containing developer. The housing 11 extends in a third direction. A housing chamber 13 is provided inside the housing 11. The developer is accommodated in the accommodating chamber 13. The housing 11 has an opening 14. The opening portion 14 is located at an end portion of the housing 11 in the second direction. The housing chamber 13 communicates with the external space of the housing 11 via an opening 14.
The agitator 20 has an agitator shaft 21 and an agitator blade 22. The agitator shaft 21 extends in the third direction. The stirring blades 22 are expanded radially outward from the stirrer shaft 21. At least a part of the stirrer shaft 21 and the stirring blade 22 are disposed inside the housing chamber 13. An agitator gear included in the gear portion 40 is coupled to one end portion in the third direction of the agitator shaft 21. The agitator shaft 21 and the agitator blade 22 rotate together with the agitator gear. When the stirring blade 22 rotates, the developer in the housing chamber 13 is stirred.
The developing roller 30 is a roller rotatable about a rotation shaft (first rotation shaft) extending in the third direction. The developing roller 30 is disposed in the opening 14 of the housing 11. That is, the developing roller 30 is located at one end portion of the housing 11 in the second direction. The developing roller 30 of the present embodiment has a developing roller main body 31 and a developing roller shaft 32. The developing roller main body 31 is a cylindrical member extending in the third direction. As the material of the developing roller main body 31, for example, rubber having elasticity can be used. The developing roller shaft 32 is a cylindrical member that penetrates the developing roller main body 31 in the third direction. As a material of the developing roller shaft 32, a metal or a resin having conductivity can be used. The developing roller main body 31 is fixed to the developing roller shaft 32 so as not to be relatively rotatable.
One end of the developing roller shaft 32 in the third direction is fixed to the developing roller gear included in the gear portion 40 so as not to be rotatable relative thereto. That is, when the developing roller gear rotates, the developing roller shaft 32 also rotates, and the developing roller main body 31 also rotates together with the developing roller shaft 32.
Further, the developing roller shaft 32 may not penetrate the developing roller main body 31 in the third direction. For example, the pair of developing roller shafts 32 may extend in the third direction from both ends of the developing roller main body 31 in the third direction.
In addition, the developing cartridge 1 has a supply roller, not shown. The supply roller is located between the developing roller 30 and the housing chamber 13. In addition, the supply roller is rotatable about a rotation shaft extending in the third direction. When the developing cartridge 1 receives a driving force, the developer is supplied from the housing chamber 13 in the casing 11 to the outer peripheral surface of the developing roller 30 via the supply roller. At this time, the developer is triboelectrically charged between the supply roller and the developing roller 30. On the other hand, a bias is applied to the developing roller shaft 32 of the developing roller 30. Therefore, the developer is attracted to the outer peripheral surface of the developing roller main body 31 by the electrostatic force between the developing roller shaft 32 and the developer.
The developing cartridge 1 has a layer thickness regulating blade, not shown. The layer thickness regulating blade forms the developer supplied to the outer peripheral surface of the developing roller main body 31 to a constant thickness. Thereafter, the developer on the outer peripheral surface of the developing roller main body 31 is supplied to a
The gear portion 40 is located at the first end face 12 as one end face of the housing 11 in the third direction. The gear portion 40 includes a plurality of gears including the above-described agitator gear and developing roller gear, a coupling 41, and a gear cover 45. The gear cover 45 is fixed to the first end surface 12 of the housing 11 by, for example, screw fastening. At least a portion of the plurality of gears is located between the first end face 12 and the gear cover 45. The coupling 41 is exposed from the gear cover 45. When the
In addition, the developing cartridge 1 has a holder cover 47. The holder cover 47 is fixed to the gear cover 45. The holder cover 47 is located on the opposite side of the housing 11 with respect to the gear cover 45 in the third direction.
The plurality of gears included in the gear portion 40 may transmit the rotational force by meshing of the teeth, or may transmit the rotational force by friction.
