摘要： The invention provides an exposure apparatus having a configuration such that, when a single laser light source having a plurality of light-emitting points is driven by a plurality of laser control apparatuses, mutual monitoring of the control state of the respective laser control apparatuses is possible, thus reducing malfunctions due to the effects of noise, and also provides a method to control this exposure apparatus, and an image forming apparatus. To accomplish this, the exposure apparatus does not execute light amount control of the light source to be driven when the determination unit has determined that another driving unit is causing the light source to be driven to emit light, and executes the light amount control of the light source to be driven when the determination unit has determined that another driving unit is not causing the light source to be driven to emit light.
