PROBLEM TO BE SOLVED: To solve problems that a drying process or a drying mechanism of ink formed on a sheet is sometimes omitted by speeding up image forming procession or miniaturization of a device and that a tip of the sheet hung down at discharge is rubbed with the sheet already discharged and thereby the image forming quality deteriorates. SOLUTION: A discharge part P as a discharge mechanism of the sheet is equipped with a discharge roller 50 connected to a driving source so as to be rotatably driven, a driven roller 51 provided on an upper part so as to be brought into contact with the discharge roller 50, and a driven roller 52 provided lower than the driven roller 51 and downstream side than the discharge roller 50 when viewed to a sheet discharge direction. A locus formed by a contact point at which the discharge roller 50 and the driven roller 51 fasten the sheet and a contact point at which the driven roller 52 is brought into contact with the sheet is a wavy curve.
