PROBLEM TO BE SOLVED: To provide an image forming apparatus that can obtain a sufficient waste paper reduction effect.SOLUTION: An image forming apparatus controls the temperature of a fixing unit before printing while conveying a recording medium through the fixing unit. The fixing unit comprises a fixing member that heats developer to be fixed to the recording medium, and has a temperature control part that controls the heating with the fixing member, a temperature detection part that detects the temperature of the fixing member, a conveying member that conveys the recording medium through the fixing unit, and a conveyance control part that controls the conveyance of the recording medium performed by the conveying member. When a direction in which the recording medium after the completion of printing is ejected is a regular direction, and a direction opposite to the regular direction is a reverse direction, the conveyance control part repeats conveyance in the regular and reverse directions of the recording medium until the temperature detected by the temperature detection part reaches a predetermined temperature.SELECTED DRAWING: Figure 1 【課題】十分な損紙削減効果を得ることが可能な画像形成装置を提供する。【解決手段】記録媒体を搬送して定着器を通過させながら印刷前の前記定着器の温度制御を行う画像形成装置であって、前記定着器は、現像剤を加熱して前記記録媒体に定着させる定着部材を備え、前記定着部材を加熱制御する温度制御部と、前記定着部材の温度を検出する温度検出部と、前記記録媒体を搬送して前記定着器を通過させる搬送部材と、前記搬送部材による前記記録媒体の搬送を制御する搬送制御部とを有し、印刷終了後の前記記録媒媒体が排出される方向を正方向、当該正方向とは逆の方向を逆方向としたとき、前記搬送制御部は、前記温度検出部の検出温度が所定温度に達するまで前記記録媒体の正逆方向への搬送を繰り返すことを特徴とする画像形成装置。【選択図】 図１
