Medium feeding device and image forming apparatus

Abstract

A medium feeding device includes: multiple transporters each including a stacking unit on which a medium is stackable in a vertical direction, a feeder that feeds air to multiple media, each of which is the medium, stacked on the stacking unit to cause the multiple media to float and separate, a delivery unit that successively delivers the media floated and separated by the feeder, and a detector that detects a state of the medium floated and separated by the feeder; and at least one processor configured to: upon detection of a state of possibility of jam or multi feeding of the medium by the detector of one of the multiple transporters during transport, switch to another transporter at a predetermined timing to feed the medium; and upon detection of the state of possibility of jam or multi feeding of the medium by the detector, change an amount of air feed by the feeder of the one transporter before being switched.
