ABSTRACT:
This invention relates to an electrophotography apparatus with a photosensitive body, first charge devices for performing a first charge process to form an image on the photosensitive body, a transfer charger for transferring the image formed on the photosensitive body onto a transfer material, and potential applying device for setting the photosensitive body at a predetermined potential by simultaneously performing a second charge process having the same polarity as a polarity of the first charge process and a full-surface exposure process on the photosensitive body, after the image is transferred by the transfer charger and before the first charge process is performed by the first charge device.
