PROBLEM TO BE SOLVED: To keep the in-machine temperature of an LED printer constant within a prescribed range and to stabilize printed result through the control of the temperature in an exposure part by controlling the action of a suction means and an exhaust means, based on the detected result by a temperature detection means. SOLUTION: A warm air generating means 51 generates warm air by utilizing heat in a developer layer 52 and a drying layer 53 in a developing part 46. The exposure part 45 is provided with the temperature detection means 54 for detecting the temperature in the exposure part 45, and a temperature control means 55 controls the suction means 49 and the exhaust means 50, based on the detected result by the detection means 54. Namely, the control means 55 controls, so that the temperature in the exposure part 45 is raised by taking the warm air into the inside by the suction means 49, when the temperature in the exposure part 45 is lower than the prescribed range, and the temperature in the exposure part 45 is lowered by exhausting the warm air to the outside by the exhaust means 50, when the temperature in the exposure part 45 is higher than the prescribed range, whereby the temperature in the exposure part 45 is made constant in the prescribed range. |
