Image Forming Apparatus, Image Forming Method, and Computer Program

摘要

An image forming apparatus includes an illuminance detecting unit (28) that detects illuminance on the image forming apparatus in which the illuminance detecting unit (28) is installed; an original detecting unit (27) that detects whether or not a target original for image formation is placed in the image forming apparatus; and a power mode control unit (49a) that performs control regarding a normal power mode/a power saving mode based on an amount of change in the illuminance detected by the illuminance detecting unit (28), based on information detected by the original detecting unit (27) regarding whether or not an original is placed, and based on an operating condition of the image forming apparatus.
