摘要： Electrophotographic photoreceptors having improved mechanical properties, electrical properties with excellent response characteristics are prepared by forming a photosensitive layer on an electroconductive substrate. The photosensitive layer contains a binder resin, which may be a polyarylate or a copolymer of polyarylate. The binder resin may be mixed with other resins up to 50 wt % with other resins to impove surface slip properties or fire retardant properties.

摘要： An image forming apparatus adopting a non-magnetic one component developing system is arranged such that a charge brush and a developing roller are aligned along the circumference of a photoreceptor drum, that is rotatably driven, in order from an upstream side in a rotating direction of the photoreceptor drum. A transfer roller is placed opposing the photoreceptor drum with a sheet transportation path in-between. The charge brush, the developing roller and the transfer roller are rotatably driven while contacting the photoreceptor drum respectively. A photoconductive layer of the photoreceptor drum is made of an organic photoconductive material, and a coefficient of friction of the photoreceptor drum and the developing roller is selected to be not more than 0.5. As this eliminates the irregularity in rotary movement of the photoreceptor, offers a quality image and reduces a driving force for the photoreceptor drum, an apparatus of a light weight and high cost can be achieved.
