Abstract: An image forming apparatus includes a latent image forming mechanism for forming an electrostatic latent image on a photosensitive member, and a developing device for supplying a developing liquid containing at least toner and a carrier liquid, to the photosensitive member on which the latent image is formed, thereby to develop the latent image. The image forming apparatus also includes a removing device for removing an excessive portion of the developing liquid supplied by the developing device, whereby the excessive portion of the developing liquid remains on the photosensitive member after development. The image forming apparatus further includes a returning mechanism for returning the excessive portion of the developing liquid, which is removed by the removing device, into a casing of a developing liquid supply unit for supplying the developing liquid to the developing device, and a reserve flow-in section.

Abstract: This invention provides an electrophotographic photosensitive body including a photosensitive layer containing a chemical substance selected from a compound having a polysilazane skeleton, a compound having an Si—CnH2n+1 bond and one of an Si—N bond and an Si—C—N bond, a compound having an Si—CnF2n+1 bond and one of an Si—N bond and an Si—C—N bond, and a mixture of a compound having one of an Si—N bond and an Si—C—N bond and a compound having a C—F bond, an intermediate transfer medium including a surface layer containing the chemical substance, and an electrophotographic apparatus using the same.
