Abstract
A method and system for forming electrophotographic images by forming on a transfer belt color toner images of, e.g., the colors of transparent, yellow, magenta, cyan and black in that order from the side of the belt. When the toner images are brought into contact under pressure with, and then transferred to, a recording medium, e.g. a copy sheet, the image on the sheet is obtained with the order of the layers reversed with the transparent toner layer as the uppermost. With the use of transparent toners having relatively large particle size to cover a plurality of underlying color toner layers formed beforehand, the efficiency in image fixing is considerably improved. In addition, by using UV curing resin as the carrier and by forming a film from the carrier itself through the curing steps by UV beam irradiation, the image fixing and surface glossiness are much improved in the electrophotographic color image formation.
