Patent ID: 7289753

Claim:
A charging device comprising: an image bearing member, which has a surface to bear an image and moves; charging means, which includes a first charging member, which charges the surface of said image bearing member; and a second charging member provided at a downstream side of said first charging member in a moving direction of the surface of said image bearing member, wherein the second charging member recharges the surface of said image bearing member; magnetic particles provided on the first and second charging members to contact said image bearing member, the first charging member charging the surface of said image bearing member and the second charging member recharging the surface of said image bearing member via said magnetic particles; magnetic members provided in the first and second charging members to hold said magnetic particles; a first magnetic pole provided in the first charging member, spaced from a first closest portion having a smallest distance between said first charging member and said image bearing member; and a second magnetic pole provided in the second charging member, spaced from a second closest portion having a smallest distance between said second charging member and said image bearing member; wherein said first magnetic pole provided in the first charging member is at the downstream side of the first closest portion in the moving direction of the surface of said image bearing member, and wherein said second magnetic pole provided in the second charging member is at an upstream side of the second closest portion in the moving direction of the surface of said image bearing member.
