Abstract
A main body of an image forming apparatus includes a switching circuit provided for switching between a normal current which should be applied at a time of normal operation and a contact-corrosion preventing current which is set larger than the normal current. Each of the currents is to be applied to an imaging unit through the contacts between the main body and the imaging unit. A control section controls the switching circuit so as to temporarily switch from the normal current to the contact-corrosion preventing current at specified timing.
