摘要： PURPOSE:To prevent the fault of a device or the irregularities of developing from occurring by uniformizing heating temperature without irregularities. CONSTITUTION:A sheet member 17 spread between a fixed shaft 15 and a movable shaft 16 is made to abut on the medium heating surface 12f of a panel 12. A piping 13 is made to go round in the panel 12. The piping 13 is connected to a container 27 through connecting pipes 25 and 26. In the container 27, a heating element heating a housed heating medium is provided and a pump making the heated heating medium circulate in the container 27 and the piping 13 through the pipes 25 and 26 is provided. Then, when a photosensitive paper P is developed, for example, the paper P is fed by a pair of supply rollers 20 and inserted between the sheet member 17 and the medium heating surface 12f. Besides, it is carried by a carrying roller 22, on the other hand, the panel 12 is heated by making the heated heating medium circulate in the container 27 and the piping 13 by the pump. Then, the paper P is heated by the heating surface 12f and ejected by a pair of ejection rollers 21.

摘要： PURPOSE:To achieve improvement in workability and a reduction in cost by sending warm air to an image carrier and controlling the temperature of a photosensitive body. CONSTITUTION:The photosensitive drum 1 (image carrier) is heated by sending warm air to a corona discharger 2 (discharge means) from a blower fan 3 (blowing means) via a heating element 21. Exhaustion is carried out by a suction fan 13 through ducts 121, 122 and 123. The temperature of the photosensitive drum 1 is adjusted by turning on/off the blower fan 3 and the suction fan 13. Since a heat source is apart from the photosensitive drum 1 and heats it with warm air, irregularities in temperature do not occur. Only the photosensitive drum 1 can be attached and detached.
