ABSTRACT:
A jam processing device comprising a plurality of paper jam detectors positioned in a paper conveying path, a device for forcedly ejecting the jammed paper and a device for selectively controlling actuation of respective components in an image forming apparatus. The jam processing device is suitable for use in an image forming apparatus that holds a sheet of paper on a transfer belt and transfers toner images from a plurality of photosensitive drums to the paper. When a paper jam is developed in the paper conveying path, a mode for forcedly ejecting the paper is initiated to charge and destaticize the transfer belt. Further, the paper is fed and ejected from the paper conveying path while each photosensitive drum is being charged and destaticized.
