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.
