Title:
ELECTROPHOTOGRAPHIC IMAGE FORMING MEMBER CONTAINING POLYURETHANE ADHESIVE LAYER
Document Type and Number:
Japanese Patent JPH04260045
Kind Code:
A
Abstract:

PURPOSE: To prevent cracks in a charge producing layer when a thin charge producing layer is formed on an adhesive which is soluble, swellable or diffusive with a solvent and then a coating liquid of a charge transfer material is applied on the charge producing layer, and to obtain a longer effective life of a soft belt-type photoreceptor of a photoreceptor belt system used for an image forming device equipped with a supporting roll of a smaller diameter.

CONSTITUTION: An electrophotographic image forming member is assembled in the following processes. A base body having an electrically conductive surface is prepared, on which a water-based dispersion liquid or latex containing a self-crosslinking polyurethane and nonself-crosslinking polyurethane is applied. The polyurethane is hardened to form a continuous adhesive layer having a semipermeable mesh structure. Then a thin uniform charge producing layer is formed on the adhesive layer, and a coating liquid soln. of a compsn. to form a charge transfer layer which is dissolved in an org. solvent and contains a film forming polymer is applied on the charge producing layer. The polymer is then hardened to form a charge transfer layer.
