ABSTRACT:
A positional misalignment correcting device includes a pattern forming unit that forms a correction pattern and a detecting unit that detects the correction pattern. The detecting unit includes one light emitting element and one light receiving element. The pattern forming unit forms the correction pattern on a transfer member such that a formation area in which the correction pattern is to be formed along a direction perpendicular to a conveying direction of the transfer member is smaller than a light-receiving area of the light receiving element.
