Abstract:
1. An image forming apparatus comprising: a photosensitive member; a light irradiating device, which includes a light source, configured to irradiate light that the light source emits on the photosensitive member; a developing device configured to adhere toner on the photosensitive member; and a determining unit configured to determine a reference value to be input to the light irradiating device, wherein the light irradiating device causes the light source to emit light with normal emitted light quantity sufficient for adhering toner on an image portion of the photosensitive member, and causes the light source to emit light with minute emitted light quantity smaller than normal emitted light quantity sufficient for preventing toner from being adhered on a non-image portion of the photosensitive member; wherein the minute emission amount is set based on the reference value to be input to the light irradiating device; and wherein the determining unit determines the reference value to be input to the light irradiating device based on information relating to relationship between a predetermined reference value, and the light quantity in the position of the photosensitive member at the time of causing the light source to emit light based on the predetermined reference value.
