Abstract

PURPOSE: To form the electrophotographic plate of superior durability, repetitive characteristics and surface smoothness by using cyanine dyes as charge genarating material and the specific compound as charge carrier material.
CONSTITUTION: The layers of about 100μ or under composed of the charge carrier material (a) composed of the compound shown by formula I (X is heterocyclic groups shown by formulas II, III, IV; Y is O, S, -CH2-, -CH=CH-; n is 0, 1, 2) 1pt. wt. and charge generating material (b) composed of cyanine dyes about 1pt.wt. or under (preferably 0.2pt.wt. or under) are formed on a substrate such as of Al plate, whereby the composite type electrophotographic plate is formed. Here, it is desirable that the charge carrier material be used as the composition compounded with about 0.5W10pts.wt. of binder resins such as acrylic resin, butyral resin, etc. to 1pt.wt. thereof. The charge generating material and charge carrier material may be used either as mixed systems or laminated systems as separate layers.
