摘要： An image forming apparatus includes a control portion that performs a double-side image forming mode after performing a single-side image forming mode on a predetermined number of sheets in a state in which a heating unit is not attached to a sheet storage portion. The control portion sets an arrival timing of a first sheet to a transfer portion in the double-side image forming mode to be later than an arrival timing of a first sheet to the transfer portion in the double-side image forming mode in a case the control portion performs the double-side image forming mode after performing the single-side image forming mode on the predetermined number of sheets in a state in which the heating unit is attached to the sheet storage portion.

摘要： 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.

摘要： An image forming apparatus has an image forming station, a mounting portion, and a fixing portion that includes a first rotatable member, a second rotatable member, a rubbing rotatable member configured to rub a surface of the first rotatable member during a rubbing treatment, and a storing portion capable of storing number information. A number of recording materials fed to the fixing portion is counted, written into the storing portion, and used to determine whether to execute the rubbing treatment. In a case in which, in sequence, the recording material is fed to the mounted fixing portion, the mounted fixing portion is removed and replaced with another fixing portion, and the removed fixing portion is remounted, both number information acquired from the storing portion and the number of recording materials fed to the remounted fixing portion are used to determine whether to execute the rubbing treatment.

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.
