Abstract
An image forming apparatus includes an exposing device including: light sources including light emitting portions and respectively for photoconductors; a deflector for deflecting light from each light emitting portion; optical systems each for using the deflected light to form an image on the photoconductor; and a first beam detector for detecting reference light deflected by the deflector. A storage stores parameters respectively for the light emitting portions. Each of the parameters relates to a writing time extending from the detection of the reference light to emission of light for exposing a surface of the photoconductor from the light emitting portion. A controller controls the timing of emission of light from each light emitting portion for exposing the surface of the photoconductor, based on a result of the detection of the reference light and a corresponding one of the parameters.
