A condition that feeds a small-size recording sheet is relaxed to improve a finishing state of the small-size recording sheet to the same degree as a large-size recording sheet. A fusing unit (3) for an image forming apparatus, which can stably feed even a thin and weak recording sheet, is provided. The fusing unit (3) includes a heat roller (15) and a press roller (16), which fuse a toner image fused to the recording sheet, and plural separating pawls (17,18). Rotatable guides (45,46) that guide the recording sheet passing through a nip portion (23) of the fusing unit (3) to a sheet discharge guide (27) while an orientation of the recording sheet is changed is provided in each of the separating pawls (17,18). Assuming that a central feed path (251) and a lateral feed path (252), which reach the sheet discharge guide (27) from the nip portion (23) through the rotatable guides (45,46), a flexion angle (¸1) of the central feed path (251) is set larger than a flexion angle (¸2) of the lateral feed path (252). |
