Abstract:
1. An image forming apparatus, comprising: a positively-charged single layer type electrophotographic photoreceptor; a charging device that has a contact charging member for charging a surface of the photoreceptor; an exposure device for exposing the charged surface of the photoreceptor to light to form an electrostatic latent image on the surface of the photoreceptor; a developing device for developing the electrostatic latent image into a toner image; and a transfer device for transferring the toner image from the photoreceptor to a transferred body, wherein the charging device applies only a positive DC voltage to the charging roller, the positively-charged single layer type electrophotographic photoreceptor has a conductive substrate and a photosensitive layer, the photosensitive layer contains a charge generating agent, charge transfer agent and binder resin together, and a yield point strain of the binder resin is 9 to 29%.
