PURPOSE:To obtain potential characteristics stable against changes of environment, such as temperature and humidity, by providing an interlayer containing a polymer of a polyether polyol compound and an isocyanate compound in a specified isocyanate to hydroxyl molar ratio in the starting composition of the polymer. CONSTITUTION:A photosensitive layer is laminated on the interlayer 2 formed on a conductive substrate 1, and the photosensitive layer may be a laminated structure functionally separated into a charge generating layer 3 and a charge transfer layer 4 or a single layer 5 having both functions. The interlayer 2 contains the polymer obtained by condensing the polyether polyol compound with the isocyanate compound in an isocyanate/hydroxyl (NCO/OH) molar ratio of 1.0-2.0, thus permitting deterioration of potential in the dark due to deterioration of barrier function under high temperature and high humidity, rise of potential in the light due to increase of resistance under low temperature and low humidity, and the like to be prevented, and stability against environmental conditions to be enhanced. |
