The shutter mechanism includes a receiving portion including an insertion port through which the waste toner discharging unit is inserted, the receiving portion having an inner space connected with an inner space of the waste toner container through the opening, a shutter member disposed in the receiving portion to be movable between an open position and a closing position, and an urging member that urges the shutter member to the closing position. The shutter member includes a ridge on an upper portion of an outer circumferential surface. The ridge has a protrusion height corresponding to a gap between the outer circumferential surface and an inner circumferential surface of the receiving portion.
