Abstract: In the conventional electrophotographic apparatus, the formation of plural images on transfer materials from an original has been achieved by forming a latent image anew on a latent image bearing member for each image to be obtained. Such repeated latent image formation is however unnecessary in an apparatus in which a latent image formed on a latent image bearing member is utilized for forming plural images on transfer materials. Such apparatus allows a faster imaging forming speed because of absence of time required for such repeated latent image formation.This invention provides such apparatus capable of identifying, when the process of image formation on the transfer materials is interrupted, the condition of the latent image on the latent image bearing member according to the period of such interruption and judging whether or not to reuse the latent image at the re-start of the image forming process, thereby enabling to obtain the images of high quality on the transfer materials without loss and within a shortest time.
