• an ejection sheet contact portion to contact the ejection sheet, the ejection sheet contact portion having a first upwardly curved face that is disposed to face the ejection sheet at a posture of the contact member lifted by the ejected sheet;
• a stacked sheet contact portion disposed opposite the ejection sheet contact portion, the stacked sheet contact portion including a contact portion to contact a stacked sheet stacked on the stacker;
• and
• a pressing portion to press the stacked sheet, the pressing portion disposed at an intersection between the ejection sheet contact portion and the stacked sheet contact portion,
• wherein the contact member includes a top portion as one end portion of the stacked sheet contact portion,
• the contact portion has a second upwardly curved face in the sheet ejection direction, and
• the top portion is protruded above a rotary shaft at a position where the contact member is lifted by the ejected sheet.
