Abstract
An image forming apparatus comprising an exposure device for exposing 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 device for calculating an exposure amount of each pixel of the monochromatic image data to expose the image bearing member with the calculated exposure amount; wherein the control device includes a monochromatic correcting device for calculating 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 the control device includes a multi-color correcting device for providing a coefficient for correction of the exposure amount on the basis of the multi-color image data; wherein the monochromatic correcting device controls the exposure amount using the coefficient and the correction amount provided by the multi-color correcting device.
