Abstract
Official abstract text for this publication.
An image forming apparatus for forming an image based on an electrophotographic process applied to image data that represents the image includes a device configured to perform a periodic movement for image formation, a storage unit configured to store a table for correcting density variation caused by the device, the table initially generated when a physical property of the device is in a reference state, a prediction unit configured to predict an amplitude of the variation caused when the physical property is in a state different from the reference state, and an adjustment unit configured to adjust the table based on the amplitude predicted by the prediction unit.
