Patent ID: 8446653

Claim:
An image forming apparatus comprising: an exposure device that exposes an image bearing member to light in accordance with monochromatic image data provided by color separation of inputted multi-color image data to form an electrostatic latent image; a control unit that calculates an exposure amount of each pixel of the monochromatic image data to expose the image bearing member with the calculated exposure amount; wherein said control unit includes a monochromatic correcting unit that calculates a correction amount in accordance with a pixel value of a pixel around a target pixel of the monochromatic image data to correct an exposure amount of the target pixel on the basis of the calculated amount; wherein said control unit includes a multi-color correcting unit that provides a coefficient for correction of the exposure amount on the basis of the multi-color image data; wherein said monochromatic correcting unit controls the exposure amount using the coefficient and the correction amount provided by said multi-color correcting unit.
