    Abstract: An image forming method, comprising the steps of forming an electrostatic image on a electrostatic image-bearing member, developing the electrostatic image with toner particles having a first shape factor (SF-1) of 100-150 and containing a low-softening point substance to form a toner image on the electrostatic image-bearing member, transferring the toner image on the electrostatic image-bearing member to an intermediate transfer member which has been voltage-applied, transferring the toner image on the intermediate transfer member to a transfer-receiving material by a transfer means which has been voltage-applied, and heat-fixing the toner image on the transfer-receiving material. The toner particles may preferably have a second shape factor (SF-2) of 100-140. The total of SF-1 and SF-2 may preferably at most 275, particularly at most 240, for improving transfer efficiency of the toner particles. The low-softening point substance may preferably be an ester wax having a long-chain (e.g., .gtoreq.C.sub.10) alkyl group. The image forming method is effective in providing a high-quality (full-color) toner image with high transfer efficiency and free from toner sticking.

    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 transfer corona current is always maintained substantially constant independently of the surface potential of a photosensitive medium and environmental conditions, to thereby prevent the amount of charge on the back side of a transfer medium from fluctuating in accordance with said surface potential and environmental conditions. In addition, a separation corona current is maintained substantially constant to thereby further improve the stability of electrostatic separation. The transfer corona current is below a critical current value whereat the corona charge passes through the transfer medium, and the separation corona imparts to the back side of the transfer medium an amount of charge substantially equal to the amount of charge provided by the transfer corona.
