To enable recovery to the normal state from the power saving state at the more suitable timing than that of the conventional art for power saving in an image formation apparatus which is turned into the power saving state.SOLUTION: An image formation apparatus 1 having the power saving mode of saving the power consumption includes: an area entry detection unit 101 which detects entry of a user to an installation area being a location where the image formation apparatus 1 is installed or a prescribed location in the vicinity of it; and a normal mode switching unit 109 which maintains the power saving mode when it is estimated that the user whose entry is detected by the area entry detection unit 101 in the power saving mode is the same as the user whose entry is detected by the area entry detection unit 101 before the power saving mode, and releases the power saving mode when it is estimated that the users are not the same.SELECTED DRAWING: Figure 3 【課題】省電力状態になる画像形成装置において、省電力化のために従来よりも好ましいタイミングで省電力の状態から通常の状態へ復帰できるようにする。【解決手段】消費電力を節約する省電力モードを有する画像形成装置１に、画像形成装置１の設置されている場所またはその付近の所定の場所である設置エリアへのユーザの進入を検知するエリア進入検知部１０１と、省電力モードであるときにエリア進入検知部１０１によって進入が検知されたユーザと、省電力モードになる前にエリア進入検知部１０１によって進入が検知されたユーザと、が同一であると推定される場合に、省電力モードを維持し、同一でないと推定される場合に、省電力モードを解除する、通常モード切換部１０９と、を設ける。【選択図】図３
