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.

摘要： A photosensitive member to be used for an image-forming apparatus can effectively suppress its wettability of the surface relative to foreign objects adhering to it and reduce the load and the mechanism necessary for cleaning the surface so as to prolong the service life of the photosensitive member and make the apparatus adapted to down-sizing. For this purpose, the wettability (W: work of adhesion) of the surface of the photosensitive member relative to toner is confined to be between 60 and 110 mN/m.
