Embodiment Construction

[0027] Since the main structure of the embodiment of the process box of the present invention is the same as that of the existing process box, only the improvement of the present invention to the existing process box will be highlighted.

[0028] figure 2 The operation principle of the photosensitive drum cleaning device for the process cartridge of the embodiment of the present invention is shown. A photosensitive drum 10 , a waste toner bin 61 , a cleaning roller 50 and a charging roller 20 are disposed in the cleaning frame 60 . The developing roller 30 forms a toner image 11 on the surface of the photosensitive drum 10 through a developing operation. As the photosensitive drum 10 rotates, when passing through the imaging medium 80 , such as paper, the toner image 11 is transferred to the imaging medium 80 by the transfer operation of the transfer roller 40 to form a printed image. After the photosensitive drum 10 has been transferred, the surface of the photosensitive ...

Abstract

A processing cartridge comprises: a photosensitive drum (10); a waste toner hopper (61); a cleaning roller (50); a shaft core (51) fixed relative to the waste toner hopper (61) and a rotatable sleeve (52). A magnetic force generating apparatus (512) is disposed on the shaft core (51), so that a magnetic surface is formed on a part of a surface of the sleeve (52) facing the photosensitive drum (10). A first sealing member (70) and a second sealing member (80) in elastic contact with the surface of the sleeve (52) are disposed at gaps between the sleeve (52) and two long sides of an opening (62) of the waste toner hopper (61). The sleeve (52) further comprises a nonmagnetic surface, the second sealing member (80) is in elastic contact with the nonmagnetic surface, and the first sealing member (70) is in elastic contact with the magnetic surface. A magnetic force exerted on waste toner at a location where the first sealing member (70) is in contact with the magnetic surface is greater than a frictional force exerted by the first sealing member (70) on the waste toner.

Description

technical field [0001] The present invention relates to a process cartridge used in image forming apparatuses such as copiers, printers, and facsimiles that form images by electrophotographic processing. Background technique [0002] A known process cartridge for a laser printer is mainly composed of a developing unit and an imaging unit, and the two units can rotate with each other in a small angle range around the same rotation axis. Such as figure 1 As shown, the developing unit mainly includes a toner bin 5 , a stirring frame 4 , a powder feeding roller 3 , a developing roller 2 and a toner thickness regulating plate 6 , and these five components are all arranged in a developing frame 7 . The imaging unit mainly includes a waste toner bin 8 , a photosensitive drum 1 , a charging roller 9 and a cleaning blade 10 , all of which are arranged in a cleaning frame 11 . [0003] In the developing unit, the toner bin 5 provides a storage space for toner and a suitable toner co...
