Image forming apparatus for performing registration and density correction control
An image forming apparatus includes a forming unit configured to continuously form, on an image carrier, first and second detection patterns for detecting relative registration amounts and a density of each of a plurality of colors; and a control unit configured to control registration and the density. The forming unit forms the detection patterns such that a leading edge developer color of a detection pattern formed on a front side among the two detection patterns, in a direction in which the detection patterns are moved by rotation of the image carrier, is the same as a trailing edge developer color of the detection pattern formed on the front side, or a leading or trailing edge developer color of a detection pattern formed on a rear side among the two detection patterns.
