Abstract: PURPOSE:To obtain an image free from irregularities and also to prolong the endurance life of a photoreceptor without sustaining a vibration and an impact when a developing device positioned on a downmost-stream side is in developing operation by starting the developing operation of the developing device positioned on the downmost-stream side, simultaneously, starting driving a developing device positioned on an uppermost- stream side in a non-developing state. CONSTITUTION:When a 1st sheet is in developing operation, the developing device 14 positioned on the downmost-stream side in a moving direction of a photoreceptor 9 is driven, simultaneously, the developing device 11 positioned on the uppermost-stream side is driven in order to develop a 2nd sheet. But at this time, a developing bias for the developing device 11 on the uppermost-stream side is turned off. Thus, yellow developer for the uppermost-stream developing device 11 comes in contact with an electrostatic latent image on the 1st sheet to be developed by the developing device 14 on the downmost-stream side, but the developing bias is turned off, that is, the developing device 11 is made in the non-developing state, so that the electrostatic latent image is not developed substantially. Besides, the electrostatic latent image is developed with black toner, then the color mixture is completely inconspicuous even though the yellow developer sticks to the latent image.

Abstract: PURPOSE: To prevent the repetition of an abrupt state change by continuing the limiting operation of the maximum heating amount until a predetermined time is elapsed even if resetting conditions are satisfied when the maximum heating amount of a heater is limited depending on the input temperature of cooling water becoming higher or lower than a predetermined value. CONSTITUTION: A controller 34 limits the maximum opening of a fuel control valve 21 to limit the heating amount of a high-temperature regenerator 1 when the cooling water inlet temperature detected by a temperature sensor 32 becomes higher than the first high-temperature set value or lower than the first low- temperature set value. Even if it is slightly lower than the first high-temperature set value or becomes higher than the second low temperature set value slightly higher than the first low-temperature set value and much higher than the second high-temperature set value, the maximum opening of the valve 21 is continuously limited to 50% until a predetermined time is elapsed. Thus, the repetition of an abrupt state change can be prevented.
