摘要： An image forming apparatus includes a controller configured to control a first and a second voltage applied to a transfer device when transferring an image to a first and a second side of a recording material, respectively. The controller controls a mode that outputs a test chart on which at least one of a plurality of first test images for adjusting the first voltage and a plurality of second test images for adjusting the second voltage is formed. In a case of forming the second test images on a second side of the test chart, and before forming the second test images, the controller forms a plurality of predetermined toner images under a same image forming condition on a first side of the test chart so that the predetermined toner images are formed on a plurality of predetermined areas overlapping each area where the second test images are to be formed.

摘要： An image forming apparatus includes an intermediary transfer member, a toner image forming unit, a rotatable transfer member, a cleaning unit, a feeding unit, a feeding portion and an executing portion configured to execute a supplying operation for supplying a supplying toner image to a cleaning portion. The executing portion forms the supplying toner image at a position including a position different from a position where an adjusting toner image for adjusting an image forming condition is formed, with respect to a widthwise direction crossing a movement direction of an intermediary transfer member provided in contact with the rotatable transfer member. The executing portion performs the supplying operation at least one time in a double-sided image forming job and does not perform the supplying operation in a single-sided image forming job.

摘要： An image forming apparatus includes: an image bearing member; an image forming portion; an intermediary transfer member; a transfer member; an executing portion capable of executing a first mode in which a transfer voltage based on a current detected when a predetermined voltage is applied to the transfer member is applied to the transfer member and capable of executing a second mode in which a transfer voltage is applied to the transfer member to provide a predetermined constant-current; and a controller enabling transition between a stand-by state where the image formation is enabled and a sleep state less than in power consumption than the stand-by state. The controller executes the first mode in a job after main switch actuation and before the transition to the sleeve state, and executes the second mode in an initial job after the transition from the sleep state to the stand-by state.
