Patent ID: 7733362

Claim:
An optical writing device comprising: a light-emitting element that emits a laser light; a rotating deflection unit that deflects the laser light and that performs a scanning with the laser light; a light-intensity detecting unit that detects a light intensity of the laser light; a current control unit that controls a current to be supplied to the light-emitting element in such manner that the light intensity of the laser light reaches a target light intensity; and an initializing unit that determines an initial current value with which the target light intensity is obtained from the light-emitting element by eliminating an influence of a noise caused by a reflected light input into the light-intensity detecting unit from the rotating deflection units, wherein the laser light that the light-emitting element emits and the reflected light reflected by the rotating deflection unit in regular reflection are both incident into the light-intensity detecting unit so that the noise is generated.
