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.

Then, the outer diameter of this photosensitive drum is configured to be gradually smaller from the vicinity of the central portion thereof in the generatrix direction to both ends in the longitudinal direction, hence making it possible to enhance the cleaning effect on residual toner.

摘要： In an electrophotographic image process, a latent image is formed on a photosensitive drum, and a toner image is formed on the latent image. The toner image is temporarily transferred onto an intermediate image-transfer element. The photosensitive drum and the intermediate image-transfer element are brought into contact at an intended contact pressure and are rotated at a prescribed relative speed. At the contact portion, fine vibrations of the photosensitive drum and the intermediate image-transfer element, which can be caused by repeated contact and separation are prevented by controlling the contact temperature between the photosensitive member and the intermediate image-transfer element to be in the range of 15 to 60° C. A kinetic frictional deviation (a standard deviation of a kinetic frictional force) is controlled to be less than the average value of the kinetic frictional force. By suppressing the fine vibration, deviation in image transfer is prevented. In addition, toner melt adhesion and foreign matter deposition is prevented, whereby image blurring is prevented.

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.
