摘要:
An image forming apparatus of the invention includes plural photoconductive bodies for forming a color image, an exposure unit to scan a laser light in a main scanning direction of each of the plural photoconductive bodies and to perform exposure, and a light amount correction unit to create, for each of the plural photoconductive bodies, light amount correction data for correcting a light amount of the laser light outputted form the exposure unit so that a light receiving sensitivity of each of the plural photoconductive bodies in the main scanning direction becomes uniform, and the light amount correction unit includes a first storage unit to store reference correction data, a second storage unit to store reference correction data, a second the reference correction data is made an absolute amount, by a relative amount correspondingly to each of the plural photoconductive bodies, and a combining unit to combine the reference correction data and the relative correction data to create the light amount correction data.
