ABSTRACT:
A transferring and fixing apparatus includes a transferring and fixing member and a pressure member in close and pressing contact with each other, forming a transferring and fixing region therebetween. A fused toner image held and heated by the transferring and fixing member is transferred and fixed into in the transferring and fixing region onto a recording paper fed to the transferring and fixing region, an end portion of the transferring and fixing region where the recording paper is fed is set to have a highest pressure in the transferring and fixing region. With this arrangement the present invention prevents micro offset phenomenon in a transferring and fixing process of toner into a recording paper in a simultaneous transferring and fixing mode, thereby achieving high picture quality.
