摘要:
An electrophotographic photoreceptor comprising a conductive substrate, a photoconductive layer formed on the substrate, and a surface layer formed on the photoconductive layer, wherein the surface layer comprises a polymer mainly composed of a siloxane bond and an imide bond. The photoreceptor has small dark decay and excellent mechanical strength and causes no image blurring under high humidity conditions and therefore can be used in a general electrophotographic process. When used in a laser printer using a coherent light source, the photoreceptor produces high quality images free from a Moire fringe.

摘要:
In an electrophotographic system, an electrostatic latent image as formed on a photoreceptor is developed with a developing agent to form a toner image thereon, a transfer paper is laid over the toner image and pressure is applied to the photoreceptor and the transfer paper so as to transfer or simultaneously transfer and fix the toner image onto the transfer paper. The photoreceptor is one having a surface protecting layer and a light-sensitive layer made of a hydrogenated and/or fluorinated amorphous silicon. The light-sensitive layer and the surface protecting layer of the photoreceptor are uniformly heated to a constant temperature. A charging device or a discharging brush or blade is used as a device of discharging the charges of the photoreceptor after the transference.
