ABSTRACT:
Since a fluorine treatment or the like is applied on a surface of an intermediate transfer belt (10), and thus, the surface bears water repelling property, when fixer (92) is supplied from a fixing apparatus (90) to surface parts of the intermediate transfer belt which are carrying a toner image, the fixer is present only on the toner parts. Namely, the fixer is not attached to surface parts which are not carrying the toner. Consequently, when the surface parts are pressed on transfer paper (P) for transferring and fixing, the fixer attached to the transfer paper is present only on the parts of the toner T. Thus, compared with a conventional case where fixer is imparted to entire transfer paper, a reduced quantity of the fixer is impregnated into the transfer paper, and thus, generation of curls and wrinkles of the transfer paper is restrained.
