Abstract
In an image forming apparatus constructing a color table corresponding to a kind of recording material, provided is an image forming apparatus which includes an engine controlling unit for outputting a vertical synchronizing signal in consideration of a time required for a controller to construct the color table. The engine controlling unit and the controller are included. The engine controlling unit notifies the controller of an assumed kind of recording material and the kind of recording material actually detected. When the two are not identical, the controller reconstructs the color table corresponding to the detected kind of recording material. The engine controlling unit does not output, to the controller, the vertical synchronizing signal for outputting image data during the time when the controller constructs the color table.
