An image forming apparatus includes a first image forming unit, a second image forming unit. In combined processing to perform two types of processing including one-sided image formation and two-sided image formation, if the one-sided image formation is performed, an image is formed on one side of the sheet by the second image forming unit. If there is an execution request for a job of one-sided image formation processing different from a combined job of the combined processing during execution of the combined job, the image formation control unit, while performing the one-sided image formation in the combined job of the combined processing by the second image forming unit, performs the one-sided image formation related to the execution request for the job of the one-sided image formation processing different from the combined job by the first image forming unit and then discharges from the intermediate discharge unit a sheet which has undergone the one-sided image formation processing in the job different from the combined job.

Image forming apparatus

There is provided an image forming apparatus including a casing in which toner is accommodated, a toner inflow portion that is provided on a side of one of ends in a longitudinal direction of the casing, a first screw that conveys the toner accommodated in the casing from one end toward the other end, a second screw that conveys the toner accommodated in the casing from the other end toward one end, and a sensor in which a detection portion is disposed at a position facing a side face of the casing provided in the longitudinal direction in order to detect an amount of toner accommodated in the casing. The longitudinal direction of the detection portion is located closer to one end than the other end, and a position in a vertical direction of the detection portion partially overlaps at least a toner conveying region of the second screw.
