Abstract

PURPOSE:To improve the transfer efficiency of a toner by blowing heated dry air to the transfer paper prior to transfer thereby dehumidifying and drying the same. CONSTITUTION:A blast duct 34 mounted to a housing 1 is disposed wit a suction port 36 near a heating roller 22, and through said port it sucks the dry air heated with a heater 21 and sicharges the same through two discharge ports 36, 37. One port 36 of the duct 34 is directed toward the top surface of transfer paper 12 prior to transfer, and the other port 37 opens in a toner box 9. A blast fan 38 is disposed in the duct 34. While the dry air discharged through the port 36 of the duct 34, it is blown to the top surface of the paper 12, and further it falls onto the paper 12 on a paper feed table 14. The paper 12 is dehumidified to have higher insulation characteristic, so that the electric charge of a toner 8 is attracted to a transfer means 11 without neutralizing with the electric charge of a transfer corotron 11. Thereby, the transfer efficiency of the toner is improved.
