US 2010/0166448 A1 · IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF

Abstract

An image forming apparatus includes an image forming unit configured to form an image on recording paper, a first control unit configured to control the image forming unit, a second control unit configured to control the image forming unit, and a power supplying unit configured to supply power, when the image forming apparatus is to operate in a normal power mode, such that the first control unit goes into a normal power state in which the first control unit can control the image forming unit, and supply power, when the image forming apparatus is to operate in a power saving mode, such that the first control unit goes into a power saving state in which the first control unit cannot control the image forming unit and the second control unit goes into a state in which the second control unit can control the image forming unit, wherein the second control unit controls the power supplying unit to supply power to the image forming unit and controls the image forming unit to perform a specific operation at predetermined timing when the image forming apparatus operates in the power saving mode.
