Abstract
A recording medium discharge mechanism which discharges a recording medium (S) into a discharge tray (14) using a sheet discharge roller (69) and a sheet discharge biasing roller (72) that confronts the sheet discharge roller (66). The sheet discharge roller (69) has a plurality of vortical teeth extending in the direction of rotation of the sheet discharge roller. When the tail end of the recording medium (S) approaches the discharge roller (69), the circumferential speed of the sheet discharge roller (69) is increased so that the recording medium (S) can be accelerated into the sheet discharge tray (14) while biasing the tail end of the recording medium (S).
