摘要：
A charging apparatus for charging a member to be charged by contacting magnetic particles to the member to be charged, includes a magnetic particle carrying member for magnetically carrying the magnetic particles, wherein the magnetic particle carrying member is provided at a longitudinal end portion of the magnetic particle carrying member with an insulative portion for electrically insulating from the magnetic particles carried by the magnetic particle carrying member; and an electroconductive member disposed for contacting the magnetic particles carried on the insulative portion, wherein an absolute value of a potential of the electroconductive member is lower than an absolute value of a voltage applied to the magnetic particle carrying member.
