PURPOSE:To enhance the mechanical durability, moisture resistance and printing resistance by forming a photoconductive layer contg. a photoconductive material dispersed in a binding resin consisting of a compound contg. a phosphate group and a thermosetting resin. CONSTITUTION:100 Parts CdS powder is dispersed in methyl ethyl ketone, and a binding resin consisting of 15 parts thermosetting acrylic resin and 0.6 part compound contg. a phosphate group such as mono(2-hydroxyethyl acrylate) acid phosphate are dissolved. The prepared material is applied to an Al drum as a support, dried, and cured by heating to form an electrophotographic receptor. Since phosphate groups are introduced into the constituent molecule of the binding resin, the affinity of the resin for the photoconductive material is increased and the dispersibility of the photoconductive material in the resin is enhanced. As a result, the receptor is provided with mechanical durability and printing resistance. |
