Claim:
An image forming apparatus for forming an image on a sheet, the apparatus comprising: an abutting and separating unit adapted to abut a first rotating body to a second rotating body, and separate the first rotating body from the second rotating body; a power supply unit adapted to control power supply in the image forming apparatus; and a control unit adapted to cause the image forming apparatus to change to a power-save mode in which power consumption of the image forming apparatus is reduced, and stop power supply from said power supply unit to said abutting and separating unit, wherein said control unit is adapted to: cause said abutting and separating unit to abut the first rotating body to the second rotating body until an elapsed time after the image forming apparatus has changed to the power-save mode reaches a predetermined time, and to separate the first rotating body from the second rotating body by supplying power from said power supply unit to said abutting and separating unit when the elapsed time after the image forming apparatus has changed to the power-save mode exceeds the predetermined time; and maintain the power-save mode by stopping power supply from said power supply unit to said abutting and separating unit after the first rotating body is separated from the second rotating body.
