Abstract
Provided is a means in which in a tandem type electrophotographic image forming apparatus, image deletion of a formed image is suppressed, passing through of a toner is suppressed, and the lifetime of an organic photoreceptor and the apparatus itself is prolonged. The invention relates to a tandem type electrophotographic image forming apparatus using an organic photoreceptor in which at least a charge generating layer and a charge transfer layer are sequentially laminated on a conductive support body, in which in at least one of combinations of two adjacent image forming units including toners having colors different from each other, a linear pressure P1 of a cleaning blade A included in the image forming unit disposed on an upstream side, and a linear pressure P2 of a cleaning unit blade B included in the image forming unit disposed on a downstream side, satisfy a predetermined relationship.
