摘要： An image-forming device in which an image is formed on a transfer material by superposing the transfer material with a photosensitive material on a heating drum. By altering a duty ratio of a control signal from a controller to a heater driver, a heater is controlled such that surface temperature of the heating drum is fixed. At times other than during image-formation, during which precise control is required, the period of the control signal (i.e., of on/off control of the heater) is lengthened. Thus, “flicker” can be suppressed.
