摘要： Premising a duplex imaging apparatus having an image carrier provided with a plurality of image carrying regions, the image deterioration phenomenon (i.e., the so-called “oil ghost phenomenon”), as might otherwise accompany the local transfer of a releasing agent from a fixing unit to the image carrier, is effectively avoided. In a mode where the image carrier 2 is provided with the plural image carrying regions, duplex mode control unit 8 includes an imaging sequence determining portion 9 for determining such a fundamental imaging sequence that when duplex images are to be formed on sheets 4 more than an image carriable number of the image carrier 2, the fundamental sequence determining portion 9 causes the image carrier 2: to carry first screen images A less than the image carriable number in a first imaging cycle of an imaging unit 1; to carry images corresponding to the image carriable number in and after a second imaging cycle so that at least second screen images B may be positioned at the front of the first screen images A; and to carry the second screen images B less than the image carriable number in the last imaging cycle.
