摘要： PROBLEM TO BE SOLVED: To provide an image forming method for forming a stable image for a long time without changes in the image by environmental changes or without inducing image blur or stripe-type or speckle-type image defects. SOLUTION: The image forming method includes an electrostatic latent image forming step to form an electrostatic latent image on an electrostatic latent image carrying body, a developing step to develop the electrostatic latent image by using toner to form a visible image, a transferring step and a cleaning step. The electrostatic latent image carrying body comprises a supporting body and a photosensitive layer containing a charge generating layer, a charge transport layer and a crosslinked charge transport layer, successively layered in this order on the supporting body. The crosslinked charge transport layer contains a reaction product of a tri- or higher functional radical polymerizable compound and no charge transporting structure with a monofunctional radical polymerizable compound having a charge transport structure. The toner is obtained in a particulate state by the reaction of an active hydrogen group-containing compound with a polymer which is reactive with the active hydrogen group-containing compound in an aqueous medium to produce an adhesive base material.

摘要： PROBLEM TO BE SOLVED: To provide a coating composition for forming a new improved overcoat layer which prolongs the service life of an organic photoreceptor by reducing a wear caused particularly by wet toner and can improve electrical and mechanical properties.
SOLUTION: The coating composition for forming an overcoat layer of an organic photoreceptor characterized by containg a polyamino-ether, an electron transport material and an alcoholic solvent, is provided. When an overcoat layer is formed using the coating composition, lowering of potential by electrostatic charge and rise of residual potential after exposure can be suppressed in electrophotographic image formation, thereby prolonging the service life of an electrophotographic organic photoreceptor. Since the overcoat layer is excellent in solvent and wear resistances to a wet toner, it can be applied particularly to an organic photoreceptor for a wet toner.
