摘要： There is provided a light-receiving member comprising a photoconductive layer provided on an electroconductive substrate, and a surface layer provided on the photoconductive layer, the surface layer comprising non-single-crystal carbon containing at least fluorine, wherein the surface layer has a ratio of the area of a peak having center in the vicinity of 1200 cm−1 or 1120 cm−1 in the infrared absorption spectrum to the area of a peak having center in the vicinity of 2920 cm−1 being in a range from 0.1 to 50. The light-receiving member allows to obtain a high-quality image without faint image or smeared image in any ambient conditions without use of heating means for the light-receiving member, and has high durability enough for maintaining such high quality characteristics. It can also prevent, by the absence of the heating means, the adhesion of low melting toners such as color toners and the unevenness in image density, generated at the rotating interval of the developer. Besides, it has a high sensitivity, is free from image defects resulting from charge leaking, and is capable of stably providing high-quality images without change with elapse of time.

摘要： A composition is provided for coating a photoreceptor having a charge generating layer and a charge transport layer. The composition includes a hole transport material, a cross-linkable film forming binder having at least one functional group that is reactive with isocyanate, a blocked isocyanate cross-linking agent and a solvent having a boiling point equal to or below the deblocking temperature. The blocked isocyanate cross-linking agent is the reaction product of an isocyanate and a blocking agent, wherein the blocking agent has a boiling point temperature equal to or below a selected deblocking temperature to allow the isocyanate to form cross-links. The invention also provides an electrophotographic imaging member with an overcoat layer comprising a cross-linked film forming binder, an isocyanate compound, a hole transport material, and optionally a surface energy reducing agent. Processes for making the imaging members are also provided.
