    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 effectively suppresses the effect of wetting the foreign matters adhered to the surface thereof, reduces the load of the cleaning unit and prolong the service life of the photosensitive member so that the image-forming apparatus may be down-sized. In the photosensitive member, the surface free energy (&ggr;) on the uppermost surface of the photosensitive member is made between 35 and 65 mN/m and the variation of the surface free energy &Dgr;&ggr; is made less than 25 mN/m during long operation.
