Abstract: PURPOSE:To improve operability, to reduce the output of a heat roller, and to minimize the installation area of a device by making an image transfer part and a development part integral with each other. CONSTITUTION:Since the development part 170 and the image transfer part 100 are provided on the lower part and the upper part, respectively, and the positions where an image sheet F and an image receiving sheet P are fed and loaded and the position where they are collected are on the same side, it is not necessary for an operator to move frequently to operate the device.
