发明名称 Charging apparatus with first and second charging members
摘要 A charging apparatus includes a first charging member of being supplied with a voltage to charge a member to be charged. A first charging member has magnetic particles in the form of a magnetic brush contactable to the member to be charged. A second charging member charges a region of the member to be charged corresponding to an end portion, in a longitudinal direction of the charging member, of the magnetic particles, wherein by the second charging member, the region has a potential of the same charge polarity of the voltage when the region reaches a charging position of this first charging member.
