Abstract

PURPOSE:To carry out a heating process to obtain a semi-fixing state which is proper to perform a correction of image for the print after a wat development, by giving an automatic control of the heat quantity or changing the speed of transport after detecting the temperature of a heating part or the room temperature in a fixing device. CONSTITUTION:A switch 8 is set at (f) and (h) during the complete fixing, and lamps 3a and 3b are turned on via circuits 17 and 19, a transistor TR22, etc. by the input of a switch 23. When the semi-fixing is carried out for correction of an image, a switch 48 is set at (e) and (g). Then the detection values of temperature sensors 12 and 13 are compared with the reference level through comparators 14 and 15, and only the lamp 3a is turned on via circuits 16, 18 and 19 plus the TR22. In case the temperature of a heating part and the room temperature are increased up to a level at which the semi-fixing is possible enough without lighting up a lamp, a picture of the semi-fixing state is produced without lighting up any lamp. Then the picture is corrected.
