Patent ID: 7729625

Claim:
An image forming device comprising: an imaging unit comprising: a rotating body that is driven to rotate and has a surface, electric potential of which changes in response to light; an exposure unit that irradiates the surface of the rotating body on the basis of input image data to form an electrostatic latent image; a developing unit that develops the electrostatic latent image using developer to form an image; and a transfer unit that transfers the image formed by the developing unit to a recording medium; a memory that stores data of a first image data, the first image data being input to the exposure unit and representing a first latent image to be formed by a first turn of the rotating body, a second image data being input to the exposure unit and representing a second latent image to be formed by a second turn of the rotating body subsequent to the first turn, and a first correction amount being used for correcting the second image data so that the density of an image transferred to a recording medium when the second image data is input to the exposure unit becomes closer to the density of the second latent image represented by the second image data; a correction amount determining unit that determines the first correction amount corresponding to the first image data and the second image data on the basis of the data stored in the memory; and a correcting unit that corrects the second image data to be input to the exposure unit, on the basis of the first correction amount determined by the correction amount determining unit.
