There is provided an image recording apparatus including: a main body with first and second transporting paths, a transporting roller pair, a recording portion, a reversal roller pair, a re-transporting roller pair, a transporting motor, first and second transmission mechanisms, and a controller. The second transmission mechanism has: a sun gear, an arm, a pendulum gear, and a gear row. The second transmission mechanism is configured to change a posture between a first posture and a second posture. The controller is configured to determine a position of the sheet, determine a size of the sheet, switch the rotation of the transporting motor under certain conditions, and increase the rotation amount of the transporting motor more for the case that the size of the sheet is determined to be not less than a transport distance than for the case that it is determined to be less than the transport distance.
