<p>PURPOSE:To prevent the occurrence of upper curl and to eliminate jamming caused by separation failure by providing a heat source device in the vicinity of a lower resist roller and warming the lower surface of a transfer material when the transfer material passes a resist roller. CONSTITUTION:When the copy start key of the operation part of a copying device main body 1 is depressed, transfer paper 4 as the transfer material is fed from an upper cassette 2 (or lower cassette 3). The transfer paper 4 fed is sent by a upper vertical carrying roller 7 (or lower vertical carrying roller 8) and is stopped at a position where its leading edge is caught between upper and lower resist rollers 9 and 10. Then, the upper and the lower resist rollers 9 and 10 start to move in timing with scanning of an optical system 21, and the image is transferred at the appropriate image position of the transfer paper 4. A copying device 1 is provided with a heater 15 inside the lower resist roller 10 and the transfer paper 4 is warmed up by it when the transfer paper 4 passes the resist rollers 9 and 10, so that the moisture of the lower surface of the transfer paper 4 is evaporated.</p> |
