Abstract
An image formation apparatus for executing image formation by exposing an image carrier with irradiation light emitted from a laser source on the basis of an input signal to drive the laser source includes a correction amount calculation unit configured to calculate, on the basis of a generated correction pattern, a correction amount to control the ON or OFF timing to drive the laser source, and a signal generation unit configured to generate, on the basis of image data and the correction amount calculated by the correction amount calculation unit, a corrected signal obtained by correcting the input signal to drive the laser source so as to form the image data by controlling the ON or OFF timing.
