Abstract
An electrophotographic apparatus is provided with a photoconductive drum including an outer peripheral surface on which a latent image corresponding to an image to be transferred is formed, and a developing device for developing the latent image by a toner. The electrophotographic apparatus further includes a housing for rotatably supporting the photoconductive drum therein and having an opening on one side, a cover member for releasably closing the opening of the housing, and a transfer charger which is attached to one surface of the cover member opposing to the photoconductive drum, and which is provided for transferring the developed image onto a sheet-like member. A pre-roller is attached to an upstream end of a housing which houses the transfer charger. The pre-roller and the photoconductive drum are positioned relative to each other so that a gap of predetermined dimension is defined therebetween.
