PROCESS CARTRIDGE AND POTENTIAL DETECTION PART

Abstract

The present description provides a process cartridge and a potential detection portion; the process cartridge includes a cartridge body, a photosensitive drum rotatably installed in the cartridge body, and a potential detection portion, configured to detect an electrical signal in the imaging region; the potential detection portion includes an initial detection portion and an end detection portion; the initial detection portion and the end detection portion correspond respectively to an initial detection position and an end detection position of a detectable region of the potential detection portion along a first direction; a maximum distance along the first direction between orthographic projections of the initial detection portion and the end detection portion in the imaging region is L1;The length of the imaging region along the first direction is L2; ​​the first direction is parallel to the direction of the photosensitive drum axis; and L1 / L2>1 / 3.;
