Image forming apparatus
First Claim
1. An image forming apparatus comprising:
- an image bearing member;
electrostatic image forming means for forming an electrostatic image on said image bearing member, said electrostatic image forming means including a flexible charge member for electrically charging said image bearing member, said charge member forming a nip between said image bearing member and itself and being supplied with an oscillating voltage, wherein electroconductive particles are provided in the nip and the electroconductive particles have an average particle size of 0.1-3 μ
m; and
developing means for developing an electrostatic image formed on said image bearing member with a developer, said developing means being capable of removing residual developer on said image bearing member, wherein a frequency f (cycle/sec) of the oscillating voltage and peripheral speed v (mm/sec) of said image bearing member satisfy the following relationship;
