CLEANING DEVICE, PROCESS CARTRIDGE AND CLEANING BLADE

摘要

PROBLEM TO BE SOLVED: To easily make the accuracy of the amount of intrusion of a cleaning blade higher, and to keep the amount of intrusion constant by always making the blade follow up the change of a drum position even when the drum position is changed because of thermal deformation due to temperature rise or because a cartridge is driven or not. SOLUTION: The cleaning blade is abutted on a photoreceptor drum via two rollers. The cleaning blade is constituted integrally with a roller bearing part and supported on a shaft provided in a frame body so as to rock. The two rollers are rotatably supported at the roller bearing part so that the amount of deflection of the blade stays constant. COPYRIGHT: (C)2004,JPO
