PURPOSE:To form an electrophotographic sensitive body prevented from deterioration of acceptance potential, high residual potential, susceptibility to temp. and humidity, and deterioration of sensitivity, and stabilized in acceptance potential and residual potential at the time of repeated uses by using a specified squarinic acid deriv. as a material for an electrostatic charge generating layer. CONSTITUTION:A charge transfer layer, the charge generating layer, and a surface protective layer low in resistance are successively laminated on a conductive substrate and the charge generating layer is formed by dispersing the squarinic acid represented by formula I as the charge generating material, preferably, in an amt. of 20-50wt% into a binder resin, such as polyvinyl butyral or various other resins. A preferable particle diameter of said deriv. is in the range of 0.05-1mum. |
