Charging member, charging device and image forming apparatus wherein deposition of magnetic particles to a member to be charged is effectively prevented

摘要

A charging apparatus includes a member to be charged having a charge retaining layer for retaining a charge and an electroconductive base. A charging member capable of being supplied with a voltage is provided to charge the member to be charged. The charging member includes magnetic particles in the form of a magnetic brush contactable to the member to be charged, wherein the member to be charged has an electroconductive member electrically insulated from the electroconductive base in a region corresponding to an end portion, in a longitudinal direction of the charging member.
