Electrophotographic image forming apparatus
First Claim
1. An image forming apparatus comprising:
- a first image bearing body for bearing an image formed with a substantially spherical toner;
a transferring means for transferring a toner image on said first image bearing body onto a second image bearing body; and
a cleaning member for sweeping away the toner remaining on said first image bearing body after a transferring operation by said transferring means, the cleaning member abutting on said first image bearing body, wherein it is simultaneously satisfied that said first image bearing body contains a fluororesin on its surface, wherein a content ratio F (% by weight) of said fluororesin is in a range of 10≦
F≦
50, wherein a surface roughness Rz (μ
m) of said first image bearing body is Rz<
5.0, and wherein a dynamic friction coefficient μ
between said first image bearing body and said cleaning member is in a range of 0.5≦
μ
≦
