ABSTRACT:
Upon occurrence of jamming in an apparatus, an electrification unit4ceases electrification of a surface of a photosensitive drum3and, simultaneously, an exposure unit5starts to expose the entire surface in a width direction to light. Further, a development unit6forms a toner adhesion region T on the photosensitive drum3and, also, stops a drum motor and a belt motor in such a manner that the toner adhesion region T stops at a transfer nip section N. Thus, it is possible to alleviate a rub between the photosensitive drum3and a conveyance belt8at the time when jamming is cleared, and to suppress generation of scratches on the photosensitive drum3and a surface of the conveyance belt8.
