PURPOSE:To remove the influence of sliding and reverse transfer to image carriers and to obtain an image of high picture quality by charging an electrostatic charger with the same polarity as the charge of a toner image passing the image carrier in an image forming station canceling image formation and disabling other image forming means in the image forming station. CONSTITUTION:In an image forming device provided with plural image forming stations Pa-Pd and a moving body 6a to be moved and passed adjacently to the image carriers 1Y-1BK to transfer images formed on the image carriers 1T-1BK by respective image forming stations Pa-Pd, the image carriers 1Y-1BK and the chargers 2Y-2BK are driven in the image forming stations Pa-Pd canceling the image formation, the chargers 2Y-2BK are operated so as to charge the image carriers 1Y-1BK with the same polarity as the charge of a toner image passed through the positions of the image carriers 1Y-1BK and other image forming means in the image forming stations Pa-Pd are disabled. Consequently, an image of excellent picture quality can be obtained even at the time of image formation in a monochromatic mode and troubles at the time of generating jam of a transfer material can be removed. |
