ABSTRACT:
A starting unit starts, in parallel with a blowing operation for a first tray, a blowing operation for a second tray that is to perform a feeding operation next. When a predetermined time elapses after starting the blowing operation for the second tray, a feeding unit switches from the first tray to the second tray, and feeds the recording medium from the second tray. When the blowing operation is performed for a number of trays before switching the trays and the number of trays is equal to or larger than a predetermined number, a control unit limits the number of trays for performing the blowing operation.
