ABSTRACT:
An image formation apparatus comprises an image formation device for forming an image on a recording material according to image information light obtained from light emitted from a light source. A detector detects the light intensity emitted from the light source. A single cooling fan is provided for cooling both the light source and the image formation device. The drive force of the cooling fan is set at either a first value or a second value. The driving force is set at the first value during a time period from a start of energization of the light source until the light intensity detected by the detector is at least the predetermined value. The driving force is set at the second value after the detected light intensity is at least the predetermined value. The first value of the driving force is less than that of the second value.
