ABSTRACT:
An image forming apparatus includes an alignment pattern and an alignment pattern detector that detects the alignment pattern. The alignment pattern is formed in such a manner that a line image of a reference color and a line image of a color other than the reference color are superposed on each other with a predetermined shift amount. An acceptance width of the alignment pattern detector is determined so that the acceptance width satisfies a relation with a writing density of the image forming apparatus and a line width of the alignment pattern, as follows:in-line-formulae description="In-line Formulae" end="lead"?[acceptance width]>[line width]/(5.0627×[writing density(dpi)]−0.5331).in-line-formulae description="In-line Formulae" end="tail"?
