Abstract

An image reproducing apparatus of the type in which a toner image formed on a charge receptor is transferred to a transfer member and is fixed on said transfer member by the application of pressure and heat by use of an intermediate transfer belt. An auxiliary pressure contact roller is disposed so as to come into contact, via the intermediate transfer belt, with a support roller forming a transfer-fixing portion, disposed inside the intermediate transfer belt and opposing a pressure contact roller via the intermediate transfer belt, so that the contact area between the support roller and the intermediate transfer belt is enlarged.
