ABSTRACT:
An image forming apparatus is disclosed, in which a photo-sensitive member is exposed by exposure means accommodated therein, and development is done substantially simultaneously with the exposure.
Three time elements, that is, charging time constant C, i.e., time until reaching of a predetermined charging potential on of the photo-sensitive member in a brushing contact region between the photo-sensitive member and a toner holder after the start of charging, exposure time constant R, i.e., time until the charging potential is attenuated by the exposure to a latent image potential, and development time or time T, during which the photo-sensitive member passes by the brushing contact region, are appropriately determined.
It is found that more satisfactory image formation is possible by setting C, R and T such as to meet relations
