Abstract: A printer processor prints out two sheets of test prints by printing a test pattern on two recording sheets of different lengths. The test pattern consists of eight straight-linear lines that are parallel to a main scan direction or a sub scan direction of an exposure section. Dimensions of designated portions of the test pattern are measured on each of the test prints, to detect skew characteristics of the recording sheets, deviations of print starting positions in the main and sub scan directions and fluctuations in transport speed of the recording sheets. Based on the detected values, a skew correcting section, the exposure section and a conveyer device for the recording sheets are controlled to correct skew of the recording sheets, the print starting positions in the main and sub scan directions and the transport speed.

Abstract: It is intended to provide an image forming apparatus and image forming method capable of obtaining a comparatively high-quality image output even under a correction mode that gives preference to processing time required for correction, and capable of suppressing interruption of image formation to the utmost under operational condition such that internal temperature changes continuously. There are saved last five detections of positional shift quantity under first correction mode that gives preference to correction accuracy for each temperature band. Under second correction mode that gives preference to processing time required for correction, there is calculated a difference of a value actually obtained through measurement and an average value of data history belonging to a target temperature band (#7 through #9). Furthermore, the difference is multiplied by a reliability coefficient of main scanning direction and that of sub scanning direction, respectively, to determine correction quantity (#10, #11). Thereby, excessive change of correction quantity is prevented.
