    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： There are provided an electrophotographic apparatus and an electrophotographic process featured by control satisfying a condition 1n(n).times.1n(S)/1n(E).ltoreq.19.0 among the localized energy level density n in the photoconductive layer of an amorphous silicon photosensitive member employed in the electrophotographic apparatus, the electric field E applied to the photosensitive member, and the surfacial moving speed S thereof. Such control reduces the photocarriers remaining in the photoconductive layer and inducing the photomemory effect, thereby suppressing the influence of a remaining latent image on the latent image generated in a next step, and providing an image of high quality without the photomemory effect, within resulting in a loss in the charging efficiency.
