Abstract

PURPOSE:To enable to control the fixing energy with a high speed of response in accordance with a picture distribution, by detecting the picture information at every line having prescribed width, and executing a laser irradiation scanning to a recording picture in accordance with a fixing data indicating whether fixing is necessary or unnecessary. CONSTITUTION:Picture information is read by a CCD camera 41 through a reflector 40. From a solid laser device 33b which is energized and controlled by a laser energizing unit 33c, a laser beam is irradiated and scanned from a projection end 33a through the reflector. According to this constitution, a picture signal of a camera 41 counts the number of black picture elements of a picture at every 3mm.X3mm. by a central control equipment of an electric equipment part E19, and high, intermediate and low density, and a rank code having no picture are prepared. A fixing control device of the electric equipment part E19 energized the laser device 33b in accordance with density based on this fixing data, and a laser beam is irradiated. In the event of a signal having no picture, a laser beam is de-energized, and scanning is stopped. In this way, it is possible to control the fixing energy in accordance with picture density of 3mm. width.
