摘要:
There is disclosed a process for manufacturing an electrophotographic photoreceptor having no coating defect, a high charging performance, an excellent stability in a repeated use, and no image quality defect. The manufacturing process comprises the steps of coating a subbing layer-forming coating solution on the conductive substrate under an environment having a dew-point temperature in the range of from 5.degree. C. to 10.degree. C.; drying the coated solution under an environment having a dew-point temperature in the range of from 10.degree. C. to 20.degree. C. to prepare a subbing layer; coating a photosensitive layer-forming coating solution on the subbing layer under an environment having a dew-point temperature in the range of from 5.degree. C. to 10.degree. C.; and drying the coated solution under an environment having a dew-point temperature in the range of from 10.degree. C. to 20.degree. C. to prepare a photosensitive layer.
