This invention discloses an image forming system and an image forming method. The image forming system includes a processor. When a human body sensor detects a person in a first region at a distance of a first distance from the human body sensor, the processor controls the human body sensor to detect a person in a second region at a distance of a second distance shorter than the first region. The processor also restores the image forming device, which is in a first power state, to a second power state with a higher power state than the first power state. When a person is detected in the second region, the processor restores the image forming device to a third power state with a higher power state than the second power state.
