Abstract

PURPOSE: To obtain a receptor having satisfactory charging characteristics in the dark and superior endurance and showing a high charge disappearing speed in the exposed part by forming a charge generating layer contg. a specified azo dye and a charge transferring layer contg. a specified hydrazone compound on an electrically conductive support.
CONSTITUTION: Charge generating layer 2 contg. ≥ 30wt% azo pigment 3 is formed on electrically conductive support 1. Pigment 3 is 4',4"-bis [2-hydroxy-3- (2,4-dimethylphenylcarbamoyl)-1-naphthylazo]-1,4-distyrylbenzene represented by formula I. Charge transferring layer 4 contg. a 20W70wt% hydrazone compound represented by formula II (where R is CH3, C2H5, OCH3 or OC2H5, n is 1W3 and two Rs may form a ring) is then formed on layer 2 to manufacture a receptor showing low charging attenuation in the dark, rapidly attenuating charges in the exposed part, and giving a superior image free from a ground stain, etc.
