Abstract
In an image forming apparatus, a charging member, image transfer member or similar contact member contacts an image carrier implemented as a photoconductive element. Even when a voltage is applied to the contact member in a relatively low temperature environment, the contact member is provided with an adequate charge potential or an image transfer potential.
