ABSTRACT:
A transfer type electrostatic copying apparatus is disclosed in which the area of a photosensitive member cleaned by a cleaning device reaches an exposure zone simultaneously or prior to the arrival of a movable portion of an optical system or an original carrier at an exposure starting position from a home position thereof. This results in clear and definite copied images being obtained. At the earlier stage at which the movable portion of the optical system or the original carrier starts moving, the photosensitive member is subjected to the cleaning process, and then the exposure process is effected when the movable portion or the original carrier is running stably. Thus, the electrostatic latent image obtained by the exposure are clear and definite and free from undesirable blurs.
