摘要： The invention provides a method for producing an electrophotographic photosensitive member such that even if abnormal grown portions called spherical protrusions 203 exist on the surface of the photosensitive member, they do not appear on images, thus making it possible to considerably alleviate image defects. The method for producing the electrophotographic photosensitive member including layers each constituted by a non-single crystal material includes the steps of placing a substrate having a conductive surface in a film forming apparatus capable of being airtight-sealed under vacuum having evacuating means and raw material gas supplying means, and decomposing at least a raw material gas by a high frequency power to form a first layer constituted by at least a non-single crystal material on the substrate as a first step; exposing the substrate with the first layer formed thereon to a gas containing oxygen and water vapor as a second step; and decomposing at least a raw material gas by a high frequency power in the film forming apparatus to form on the first layer a second layer including an upper blocking layer constituted by a non-single crystal material as a third step.

摘要： An electrophotographic process is implemented with improved ghost memory and with high chargeability even under circumstances of increased process speed or compactified structure and the electrophotographic process forms an image on a photosensitive member having a photosensitive layer through a series of steps including steps of charge elimination, charging, latent image exposure, and development to form a toner image, wherein light used in the latent image exposure step is light of a wavelength within such a range that a value of (optical memory before charging)/(sensitivity) of the photosensitive layer is not more than 1.5 times a minimum value. The optical memory before charging means lowering in chargeability due to light irradiation before charging.
