Contact type charging device having voltage limiter |
摘要 |
A contact type charging device having a contact member for making contact with the surface of a charge bearing member so as to apply an electric charge to the surface in an image forming apparatus of the electrophotographic type, and having a charging device which has a high resistance resistor connected serially to the contact member so as to apply a voltage to the contact member. The contact type charging device has a regulating member for regulating the upper limit of the absolute value of the voltage applied to the contact member to prevent excessive current flow to the contact member, or has a regulating member for regulating the lower limit of the absolute value of the voltage applied to the contact member to prevent a greater than necessary drop of the voltage applied to the charge bearing member.
