Abstract: An electrophotographic process includes the steps of forming a visible image composed of coloring particles on a photosensitive member having a surface insulating layer, providing the visible image with an electrostatic charge by first corona discharge, bringing a transfer sheet into contact with the photosensitive member, providing the rear surface of the transfer sheet with a predetermined amount of an electrostatic charge of a polarity opposite to that of the charge on the coloring particles by second corona discharge thereby transferring the visible image onto the transfer sheet, and providing the rear surface of the transfer sheet with an electrostatic charge, which is the same in polarity as that of the coloring particles but is less in the amount than that provided by the second corona discharge, thereby separating the transfer sheet from the photosensitive member, and an apparatus adapted for executing the above-mentioned process.

Abstract: An image developing device capable of forming a magnetic brush of one-component developer on a developer-feeding magnetic brush roller, and bringing said magnetic brush into contact with a developing roller to form a thin layer of the one-component developer thereon. In the mutually facing area between the rollers the magnetic force of the developing roller for transporting the developer is selected smaller than that of the magnetic brush roller for transporting the developer. The magnetic brush roller and the developing roller are rotated in a same direction so that they are moved mutually oppositely at the mutually facing area thereof.

Abstract: A cleaning apparatus for an electrophotographic apparatus comprising an elastic cleaning blade with a holder arranged along a surface of a photosensitive member for cleaning the toners which still remain on the surface of a photosensitive member even after transferring of developed images to a copying paper is finished. The elastic cleaning blade preferably contacts with the surface of the photosensitive member in such a way that the axis of the blade and a tangent to said surface at the pre-cleaning side subtends an obtuse angle specified in relation with the axis line of the blade in the holder. The holder disposes the elastic cleaning blade relative to the photosensitive member to engage a substantially upwardly moving surface portion of the photosensitive member.
