PURPOSE:To obtain an electrophotographic receptor good in repetition fatigue characteristics, by vapor-depositing a selenium material having width of peak temps. of exothermic reaction measured by differential thermal analysis in a specified range on a substrate to form a photosensitive layer. CONSTITUTION:The selenium material, such as selenium or its alloy, such as selenium and tellurium alloy is analyzed by the differential thermal analysis, and the material is selected having temp. width measured of the peaks (temp. difference between the initial peak temp. and the end peak temp.) of exothermic reaction within the range of 8-30 deg.C. The selected material is vapor-deposited onto the substrate of aluminum or the like to obtain the intended electrophotographic receptor low in fatigue. The differential thermal analysis is conducted in the following conditions: alpha-Al2O3 as the standard sample, chromel-alumel as the thermocouple are used, and + or -250muV differential heat, and 10 deg.C/min temp. rising speed are adopted. |
