摘要： An image forming apparatus includes a mounting portion that detachably mounts either one of a fixing portion and another fixing portion. Each fixing portion includes a first rotatable member and a second rotatable member that, together, form a nip for fixing a toner image on a sheet, and a memory. A rubbing rotatable member executes a rubbing process of rubbing a surface of the first rotatable member, and a moving mechanism moves the rubbing rotatable member between a rubbing position, in which the rubbing rotatable member is in contact with the first rotatable member, and a stand-by position, in which the rubbing rotatable member is separated from the first rotatable member. In addition, a controller stores information corresponding to an execution frequency of the rubbing process designated by an operator through an operating panel, in the memory of the fixing portion that has been mounted in the mounting portion.

摘要： Provided is an image forming apparatus capable of reducing power consumption by optimizing preliminary operation of a sensor. In the image forming apparatus, when tone characteristics adjustment is instructed (Step S1003: Y), tone characteristics adjustment (Step S1006) is executed after calibration (Step S1004), while when mixed-color correction is instructed (Step S1007: Y), mixed-color correction processing (Step S1009) is executed after calibration (Step S1008). Further, in the case where mixed-color correction is executed after tone characteristics adjustment, the preliminary light emission time in calibration is set shorter than when mixed-color correction is executed without performing gray adjustment first.

摘要： A sheet conveying apparatus that restricts conveyance of sheets to a post-processing apparatus which has become incapable of continuing a post-processing operation. The sheet conveying apparatus is communicably connected to the post-processing apparatus that performs post-processing on a sheet bundle formed by sheets. The sheet conveying apparatus includes a conveying unit for conveying sheets and an escape tray for receiving conveyed sheets which are not conveyed to the post-processing apparatus. A value corresponding to the number of sheet bundles formed by conveyed sheets is counted. A CPU circuit section determines based on communication with the post-processing apparatus whether or not the post-processing operation can be continued thereby. When it is determined that the post-processing operation cannot be continued, the CPU circuit section switches the sheet conveying destination from the post-processing apparatus to the escape tray, based on the counted value.

摘要： An image forming apparatus, includes: a conversion unit configured to convert image data based on a conversion condition corresponding to a halftone process type; an image processing unit configured to perform a halftone process to the image data; and a controller configured to control an image forming unit to form a predetermined measurement image on an image carrier, to control the measurement unit to measure the predetermined measurement image, and to generate a predetermined conversion condition corresponding to a predetermined halftone process type based on a measurement result. In a case where the predetermined halftone process type is not performed by the image processing unit from when the predetermined measurement image is formed last time, the controller skips formation of the predetermined measurement image by the image forming unit.
