摘要： A blade-like charging member comprises a charging portion, a non-charging portion, and an electrode portion. The non-charging portion is capable of contacting the image bearing member while maintaining an electrically dischargeable gap therebetween. To prevent electric discharge between the non-charging portion and the surface of the image bearing member, at least part of the non-charging portion is made of material having a higher resistance than that of the charging portion. The non-charging portion contacts and slides on the surface of the image bearing member over a range that exceeds the length of the charging portion. A shortest distance between the discharge position and an end portion of the electrode portion with respect to a longitudinal direction of the image bearing member is longer than a shortest distance between the discharge position and a central portion of the electrode portion with respect to the longitudinal direction of the image bearing member.
