Abstract:
An image forming apparatus includes: an image former that forms a document image including a correction image; an image reader; and a calibrator, and performing correction, wherein the document image is designed so that main register marks and a subsidiary register mark are provided, and the calibrator includes a four-corner detector that detects four corners of a sheet of paper, a main register mark reference position detector that detects reference positions of the main register marks, a subsidiary register mark prediction position determiner that predicts and determines prediction positions of the subsidiary register marks, a subsidiary register mark reference position detector that detects a reference position of the subsidiary register mark, a correction image prediction position determiner that predicts and determines a prediction position of the correction image, a measured value obtainer, and a correction value calculator.

Claim (Index 14):
The calibration method according to  claim 9 , wherein\n a second subsidiary register mark is provided between the main register marks and the subsidiary register mark in the document image, according to the correction function or a size of the sheet, and in the determining of the prediction position of the subsidiary register mark, a position of the second subsidiary register mark in the read image data is predicted according to the detected reference positions of the main register marks and the reference positions of the main register marks in the document image data, and a prediction position of the second subsidiary register mark is determined, a reference position of the second subsidiary register mark is detected in the vicinity of the prediction position of the second subsidiary register mark, and the position of the subsidiary register mark in the read image data is predicted according to the detected reference position of the second subsidiary register mark and the reference position of the second subsidiary register mark in the document image data, and the prediction position of the subsidiary register mark is determined.
