An image forming apparatus to form an image on a sheet of recording media includes a discharge port formed in an upper portion of a main body of the image forming apparatus and exposed from above, a discharge portion to which the sheet is discharged, disposed downstream from the discharge port in a direction in which a sheet is discharged, a discharge roller disposed at the discharge port, a facing member disposed facing the discharge roller, forming a discharge nip together with the discharge roller, and a rotatable sheet discharge member. The sheet discharge member is provided in the discharge portion to form a sloped portion continuous with a downstream side of the discharge port in the direction in which the sheet is discharged. Rotation of the sheet discharge member causes a position of the discharge nip to change.
