PROBLEM TO BE SOLVED: To provide an image forming device capable of satisfactory image formation free of the occurrence of base exposure. SOLUTION: The previous amount of UCR is adjusted to 50%. More toner is attached to the same PWM line, in comparison with a normal mode. As a result, the toner on sheet fibers increases, which prevents the toner from melting from the top of the fibers during a heat fixing operation. Accordingly, satisfactory image quality in which the base is not exposed can be obtained. |
