On the basis of embodiment 1, as shown in fig. 7, the toner hopper further includes a dredging mechanism 6, the dredging mechanism 6 is disposed on the second fixing cylinder 18, the dredging mechanism 6 is configured to dredge the toner in the second fixing cylinder 18, the dredging mechanism 6 includes a fourth fixing block 61, a seventh sliding frame 62, a tenth return spring 63, a guide block 64, and a soft strip 65, the fourth fixing block 61 is fixedly connected to the second fixing cylinder 18 in a distributed manner, the second fixing cylinder 18 is connected to two seventh sliding frames 62 in a lifting manner, the seventh sliding frame 62 contacts with the sixth sliding frame 53, the seventh sliding frame 62 is connected to a pair of tenth return springs 63, one end of the tenth return spring 63 far away from the seventh sliding frame 62 is connected to the fourth fixing block 61, two pairs of guide blocks 64 are symmetrically disposed on the inner wall of the second fixing cylinder 18, the bottom of the seventh sliding frame 62 is fixedly connected to the soft strip 65, the soft strip 65 is configured to dredge the toner in the second fixing cylinder 18, the guide block 64 is slidably connected with a flexible strip 65, and the flexible strip 65 is tightly attached to the second fixed cylinder 18.

During the downward movement of the fixing strip 32 and the device thereon, the second fixing plate 37 contacts the seventh sliding frame 62, the second fixing plate 37 pushes the seventh sliding frame 62 and the soft strip 65 to move downward, and the soft strip 65 unblocks the toner in the second fixing cylinder 18 to prevent the toner poured again from blocking the second sliding frame 19.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
