PURPOSE:To obtain a electrophotographic sensitive body low in residual potential and superior in durability or the like without considering a combination between an electrostatic charge transfer material and a binder by incorporating a specified metal compd. in a charge transfer layer and forming a laminate type photosensitive layer composed of the charge transfer layer and a charge generating layer. CONSTITUTION:The charge transfer layer contg. at least one kind of oxide or chloride of a metal, such as Fe, Ni, Cu, Cr, Sn, In, Ag, or the like together with a charge transfer layer is formed in combination with the charge generating layer on a conductive substrate. The charge generating layer is formed on the conductive substrate by vapor depositing the charge generating material, such as Se, Se alloy, amorphous Si, or org. pigment, or incorporating it in the binder and coating the substrate with the binder contg. it. The charge transfer layer is formed on the charge generating layer. The addition of the metal compd. makes it unnecessary to consider the conventional problems that the residual potential depends on the combination between the charge transfer material and the binder, and repeating the use increases residual potential, thus permitting the photosensitive body to be extended in life. |
