Abstract:
A blade-like charging member for charging a surface of an image bearing member by contacting the image bearing member and by being supplied with a voltage. The blade-like charging member includes a charging portion for effecting electric discharge to the surface of the image bearing member, and a non-charging portion not effecting the electric discharge to the surface of the image bearing member. The non-charging portion is capable of contacting the image bearing member while maintaining an electrically dischargeable gap between the charging portion and the image bearing member. At least a part of the non-charging portion is made of a material having a higher resistance than that of the charging portion so as to prevent electric discharge between the non-charging portion and the surface of the image bearing member.
