Position detector, image forming apparatus, position detecting method, and non-transitory recording medium storing position detecting program code

A non-transitory computer-readable recording medium storing executable program code, wherein the program code, when executed, instructs an apparatus to execute a position detecting method comprising:

• detecting a position of a mark on a position reference member by a reading device;
• detecting a contour of a processing target and a position of a pattern on the processing target;
• and
• correcting a processing position for the processing target to offset distortion of the reading device based on the detected position of the mark, the detected contour of the processing target, and the detected position of the pattern on the processing target.
