PURPOSE:To obtain the titled material having a stabilized charge potential and residual potential by laminating an electric charge transfer layer, an electric charge generating layer and a surface protective layer having a low resistance in this order, and by dispersing one kind of the compd. selected from the group composed of a specific phthalocyanine derivative in the electric charge generating layer. CONSTITUTION:The titled material is formed by laminating the electric charge transfer layer 12, the electric charge generating layer 11 and the low resistance surface protective layer 10 on the conductive substrate 13 in this order, and the one kind of the compd. selected from the group comprising the phthalocyanine derivatives shown by formula (I), (II), (III) or (IV) is dispersed in the electric charge generating layer. The electric charge generating layer comprises the phthalocyanine derivative as an electric charge generating substance, and is formed by dispersing said derivative in a binding resin in an amount of 5-90wt%, preferably 20-50wt% on the weight basis of the total body. The particle size of the phthalocyanine derivative is 0.02-3mum, preferably, 0.05-1mum. The film thickness of each layers is 5-40mum in the electric charge transfer layer, <=5mum in the electric charge generating layer and 0.5-20mum in the surface protective layer having the low resistance, respectively. Thus, the titled body having the stabilized charge potential, even in case of a repeated use, is obtd. |
