摘要： An image forming apparatus includes an image carrying body on which a toner image is created. A sheet carrying/transporting rotational body adsorbs a recording sheet to which the toner image on the image carrying body is transferred, and transports the sheet. The recording sheet is detached after transfer from the sheet carrying/transporting rotating body, and an assisting device thrusts against the non-image area of the recording sheet to limit its detachment from the sheet carrying/transporting rotating body. The image forming device can prevent transportation failure and image smudging that is otherwise generated when a thick sheet provided with a curl before it is adsorbed to a sheet carrying/transporting rotational body is detached in the curved state from the rotational body and transported to a fusing means.

摘要： A heated roller type of fixing device to prevent offsetting of toner onto a fixing or pressure roller and an imaging system including such a fixing device wherein a sheet with toner deposits thereon is passed between a fixing roller and a pressure roller to fix the toner in place, a releasant applicator applies a releasant on the surface of at least one of said fixing or pressure rollers, and a releasant remover removes from the sheet the releasant deposited thereon by the fixing or pressure roller, thereby the releasant remaining on the toner image is removed by the releasant remover. Thus, it is possible to eliminate image density variations which may otherwise be caused by an uneven distribution of the releasant, as is the case with the prior art, and to obtain an image density which does not change with time and so is stable.

摘要： A sheet straightening unit including a device for pushing a depressing roll against an endless belt, so that a curled sheet is straightened when passing between the endless belt and the depressing roll pushed against the latter. The depressing roll is provided with an amount-of-depression adjusting mechanism which includes a cam member and a cam follower member engaged with the former, in such a manner that the cam member is turned according to the kind and image density of the curled sheet, thereby to most suitably determine the extent to which depressing roll is pushed against the endless belt.

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.
