Abstract
A charging member for charging a member to be charged and an image forming apparatus provided with the same have electrically conductive particles and an electrically conductive particle bearing member having elasticity and bearing the electrically conductive particles thereon, and the degree of cohesion of the electrically conductive particles is 0.1 to 85%. Thereby, the non-uniformity of a halftone image peculiar to particle charging can be improved.
Claims23
A charging member for charging a member to be charged, having:
- electrically conductive particles;
- and
- an electrically conductive partial bearing member having elasticity and bearing said electrically conductive particles thereon;
