An image forming apparatus includes an image forming unit, a human-body detection unit, an instruction receiver, and a controller. The controller determines whether an adjustment process is to be performed in accordance with a result of a determination, at an end of an image forming process, as to whether a human body is detected. The controller executes the adjustment process when the image forming process is terminated where the human-body detection unit does not detect a human body. The controller starts the image forming process before the adjustment process is executed where a human body is detected and the image forming instruction is received within a predetermined period. The controller executes the adjustment process when the predetermined period has elapsed while the image forming instruction is not received after the end of the image forming process where the human-body detection unit detects a human body.
