Abstract

PURPOSE:To make stable flash fixing possible without the influence of ambient temps., by controlling the electric charge quantity for flash emission of a fixing lamp according to the temp. of recording paper formed with images. CONSTITUTION:The temp. of the recording paper which is already formed with images and is conveyed to the device is detected with a temp. detecting part such as thermistor 200, and the temp. detecting voltage is a reference voltage of an operational amplifier 210 of a charging voltage control circuit 115. A charging voltage of a main capacitor 110 for flash emission of a fixing lamp 114 is applied to this amplifier 210, and when the charging voltage to the capacitor 110 attains the reference value, the supply of the charging power to the capacitor 110 is stopped by a solid state relay 101. Therefore, the quantity of flash light of the lamp 114 is controlled automatically in accordance with the temps., and the stable flash fixing without influence of ambient temps. is accomplished.
