ABSTRACT:
Disclosed is an electrophotographic plate having a laminated structure comprising a first Se layer containing 3 to 10% by weight of As, a second Se layer containing 40 to 47% by weight of Te and 3 to 10% by weight of As and a fourth Se layer consisting solely of Se or comprising Se and up to 10% by weight of As or an organic semiconductor layer, wherein a substrate is arranged so that at least the face of the substrate which is contiguous to the face of one of said first Se layer and said fourth Se layer or organic semiconductor layer, that is located on the outer side of the laminated structure, is electrically conductive.
It is preferred that the fourth Se layer be formed by vacuum evaporation deposition while maintaining the substrate temperature at 50.degree. to 80.degree. C. The residual potential of the electrophotographic plate can be reduced.
