To provide a printing apparatus that starts printing a print job in a short time while suppressing power consumption by detecting and authenticating an operator approaching a main body and confirming that a print job of an authenticated operator is registered externally, and thus controlling a power state for each device finely.SOLUTION: An image forming apparatus controls each device that performs image processing and controls communication with a server device storing a print job received from an information processing device, and, in response to detection of an operator, after transitioning a power state from a third power state to a second power state, based on a response from the server device, controls the power state so as to transition the power state from the second power state to a first power state or to maintain the second power state.SELECTED DRAWING: Figure 10 【課題】本体に近づく操作者を検知し、認証し、当該認証した操作者の印刷ジョブが外部に登録されることを確認することで、各デバイスに対する電力状態をきめ細かく制御できるため、消費電力を抑えつつ、短時間で印刷ジョブの印刷を開始する。【解決手段】画像処理を行う各デバイスを制御し、かつ情報処理装置から受信した印刷ジョブを保存するサーバ装置との通信を制御する画像形成装置において、操作者が検知されることに応じて、電力状態を第３の電力状態から第２の電力状態に遷移させた後、サーバ装置からの応答に基づいて、電力状態を前記第２の電力状態から第１の電力状態に遷移させ、または第２の電力状態を維持させるように電力状態を制御する構成を特徴とする。【選択図】図１０
