Abstract: 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.

Abstract: A sheet conveying apparatus capable of continuing conveyance of sheets without causing a jam even when a switching member performs an operation for switching a conveyance path again. A switching member is disposed at a branching point of a conveyance path through which the sheet is conveyed by a conveying unit, and is operated by a drive unit for witching a destination of conveyance of the sheet. A controller causes the drive unit to operate the switching member, and performs a checking operation for checking a state of the drive unit based on an output from a sensor that detects a state of the switching member. The controller controls a sheet conveyance interval between a first sheet conveyed by the conveying unit and a second sheet conveyed following the first sheet, according to a result of the checking operation.

Abstract: An image forming apparatus which performs an adjustment operation at appropriate timing. Whether to execute a first or a second adjustment processes is controlled based on the number of sheets on which images are formed. A first adjustment operation is executed in a case where the number of sheets has reached a first number since a previous first adjustment process was executed. A second adjustment operation is executed in a case where the number of sheets has reached a second number since a previous second adjustment process was executed. The first adjustment operation is executed in a case where the number of sheets has reached the first number prior to a designated time by a predetermined period. The second adjustment operation is skipped in a case where the number of sheets has reached the second number prior to the designated time by the predetermined period.

Abstract: 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.
