Abstract: An image forming apparatus can prevent generation of correction data without setting a proper test original. A mat is closed for pressing an original on a platen. An opening/closing sensor detects a closed state and an open state of the mat. A density correction section corrects image data based on a correction condition. A printer forms an image based on the image data. A CPU controls the printer to form a pattern on a sheet, controls a CCD sensor to acquire read data concerning an image of the original according to user instruction for the CCD sensor to read the original, and generates the correction condition based on the read data. When the user instruction is given, if the open state of the mat is not changed to the closed state, the CPU displays a screen prompting the user to place the sheet on the platen.

A corrected digital image is determined by resampling the image lines of a digital image responsive to the cross-track position correction function.
