A controller for controlling an image forming apparatus having a light detection unit controls at least two operations including: 1) operation of detecting a jam of a recording sheet in a sheet transfer path based on a light intensity level detected by the light detection unit when image forming is performed; and 2) operation of controlling switching of an operation mode of the image forming apparatus to an energy save mode based on a light intensity level detected by the light detection unit. |
