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.

摘要： Image deterioration (so-called oil ghost) due to local transfer of a release agent from a fuser to an intermediate transfer body is effectively prevented. The fuser has a pair of fixing members, a release supply mechanism, an interlocking mechanism, and an interlocking control mechanism. The fixing members are in contact with each other and roll over each other, thus nipping a sheet. The fixing members fix unfixed images on the sheet. The release agent supply mechanism is mounted to at least the fixing member located on the surface of the sheet carrying an unfixed image. The release agent supply mechanism supplies a release agent to this fixing member at a constant rate. The interlocking mechanism interlocks the fixing members and release agent supply mechanism with each other such that the fixing members are kept in contact with each other and roll over each other and that a release agent is supplied to the fixing members. When duplex mode is selected, the interlocking control mechanism controls the interlocking time of the interlocking mechanism according to the length of the path of the sheet going to the nip between the fixing members.

摘要翻译： 有效地防止了由于脱模剂从定影器局部转移到中间转印体而导致的图像劣化（所谓的油重影）。 定影器具有一对固定构件，释放供给机构，联锁机构和互锁控制机构。 固定构件彼此接触并且彼此滚动，从而夹住片材。 固定构件将未固定的图像固定在片材上。 脱模剂供给机构至少安装在位于载有未定影图像的片材的表面上的固定构件。 脱模剂供给机构以一定的速度向该固定部件供给脱模剂。 互锁机构将固定部件和脱模剂供给机构互相联结，使得固定部件保持彼此接触并且彼此滚动，并且将脱模剂供给到固定部件。 当选择双面模式时，互锁控制机构根据到达固定构件之间的辊隙的片材的路径的长度来控制互锁机构的联锁时间。
