Abstract
An image forming apparatus having at least: an image carrying member for carrying an electrostatic latent image, the image carrying member having a photosensitive layer on a conductive substrate; a developer for developing the electrostatic latent image carrying member on the image carrying member; a developer carrying member for carrying the developer and conveying it to a development area; a control member making contact with the developer carrying member for controlling the coating amount of the developer; and a cleaning member for cleaning the surface of the photosensitive layer of the image carrying member by making contact with the surface of the image carrying member with a contact pressure of 0.15N (15 gf) to 0.89N (90 gf). The photosensitive layer contains at least one kind of polycarbonate resin (I) having a viscosity average molecular weight of 1.5.times.10.sup.4 or less and at least one kind of polycarbonate resin (II) having a viscosity average molecular weight of more than 1.5.times.10.sup.4, the polycarbonate resin (I) is contained in 30% by mass to 95% by mass based on the total content of the resins (I) and (II). The developer has a toner containing toner particles…
