ABSTRACT:
An image forming apparatus including: a reflection member to reflect light at a first position spaced a predetermined distance from a scan glass; a moving unit to move the reflection member between the first position and a second position; and a control unit to generate initial reference data from an image signal transmitted from a scanning device to receive the light reflected by the reflection member. When the initial reference data is not suitable for shading correction, the control unit controls the moving unit to move the reflection member to the second position for reference data reacquisition.
