Abstract
A liquid-development full-color electrophotographic apparatus utilizes a development section having a liquid toner as a liquid developer to form a toner image according to an electric field established between the development section and a photosensitive drum. The toner image is transferred from the photosensitive drum onto an intermediate transfer roller according to an electric field established between the intermediate transfer roller and the photosensitive drum, from the intermediate transfer roller to an intermediate transfer belt, and then to a transfer-and-fixation section, which melt-transfers the toner image onto a printing medium. A voltage controlled according to electric characteristics of each color toner is applied to the corresponding photosensitive drums while the roller is grounded. A toner cohesion enhancement unit is provided for enhancing the degree of toner cohesion of a toner image transferred and reverse transfer is suppressed.
