Image forming apparatus

An image forming apparatus (1) includes a human body sensor (21), a microphone (22), a receiving unit (103), and a control unit (100). The control unit (100) sets the microphone (22) to a state in which voice can be input when the image forming apparatus (1) is set to a power-saving state and a person approaching the image forming apparatus (1) is detected by the human body sensor (21). And a control unit (103) for releasing the operation mechanism necessary to execute the function associated with the content indicated by the voice instruction received by the reception unit (103) from the power-saving state and setting the operation mechanism to the normal operation state, and maintaining the operation mechanism necessary to execute the function not associated with the content indicated by the voice instruction in the power-saving state. 图像形成装置(1)具备人体传感器(21)、麦克风(22)、接受部(103)以及控制部(100)。控制部(100)在将图像形成装置(1)设为省电状态时，在由人体传感器(21)检测到接近者的情况下，将麦克风(22)设为能够输入语音的状态，将执行与接受部(103)接受到的语音指示所表示的内容建立对应关系的功能所需的动作机构从省电状态解除并设为通常动作状
