摘要:
An image forming apparatus of the present invention carries out an image processing with respect to a sheet size based on a print request and image information based on the print request, so as to obtain a write image on a photoreceptor. On the basis of a printing ratio of the write image obtained by the image processing, the image forming apparatus predicts the occurrence of an image elongation. If the image forming apparatus predicts that the image elongation occurs, the image forming apparatus calculates a bending amount of a bended portion on the basis of the difference between the peripheral velocity of a photoreceptor and the peripheral velocity of the idle roller, and the image forming apparatus variably controls the peripheral velocity of an idle roller so that the bending amount calculated is adjusted so as not to cause a slip phenomenon. With this, it is possible to avoid the occurrence of a phenomenon of slipping of a sheet with respect to the photoreceptor without lowering the image quality, and also possible to surely secure a blank space formed at a rear edge portion of the sheet.
摘要:
A first control member is disposed in a drum shaft away from a photoconductive drum, and a second control member is disposed in a roller shaft away from a transfer roller. The first and second control members abut on each other at their circumferential surfaces. This helps reduce an amount of displacement resulting from an impact caused by insertion of a recording paper sheet in between the photoconductive drum and the transfer roller, and thereby reduce vibrations in the photoconductive drum. Consequently, a toner image formed on the photoconductive drum and an unfixed toner image transferred onto the recording paper sheet are not affected by vibrations, so that a high-quality image is obtained that is free from blurriness or irregularities.
