    摘要： 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.

    摘要： An electrostatic latent image developing method and a device therefor, featured in supplying one-component magnetic developer onto a developer-feeding non-magnetic bearing member to form thereon a magnetic brush of developer under the effect of a magnetic field, then bringing said magnetic brush into contact with the surface of an image-developing developer bearing member to form thereon a thin uniform layer of the developer, and bringing said thin layer to a developing position to develop an electrostatic latent image formed on a latent image bearing member. At the development the thin layer of the developer is so spaced in the developing position from the latent image bearing surface as to form a clearance therebetween, across which an AC bias electric field is applied.

    摘要： 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.
