The apparatus includes a CPU which executes, based on a detection result of a BD sensor, start-up control for controlling driving of a scanner motor, so that a rotation number of the scanner motor reaches a predetermined rotation number, and executes determination control for determining a voltage to be applied to a primary transfer unit based on a detection result of a transfer current detection circuit by a transfer voltage output circuit upon execution of image formation, and when an image forming station K which executes image formation is different from an image forming station Y including the BD sensor, the CPU parallelly executes the start-up control and determination control. |
