摘要： An image formation process which forms a toner image by the nonmagnetic one-component developing system by bringing an electrically conducting brush impressed with a voltage into contact with a photosensitive material to effect the uniform charging, and forming an electrostatic latent image on the photosensitive material by the exposure to the image-bearing light, wherein the toner that is used as a circularity of from 0.92 to 0.98. The nonmagnetic one-component developing system minimizes irregular electric charging that stems from the use of the electrically conducting brush. This action is obtained even in full-color developing system which effects development many times.

摘要： Provided are an electrophotographic method and an electrophotographic apparatus that can reduce ghost memory latent in an a-Si photosensitive member, relieve potential unevenness, and provide image copies with high quality. In an electrophotographic process of forming a toner image at least through decharging of a photosensitive member as a recording element, charging, exposing, developing, and transferring, at least a light-receiving layer of the photosensitive member is comprised of an amorphous material; a latent image is formed by the exposing with a light; the light has such a peak wavelength in an emission spectrum as to make minimum a value of optical memory at a unit contrast potential; and the decharging is implemented by use of a light having a full width at half maximum of a peak in an emission spectrum of not more than 50 nm.
