Abstract
A color image formation apparatus of this invention includes a density adjustment sensor which detects a density adjustment mark arranged at a position at which a detection area of the density adjustment sensor does not overlap with detection areas of alignment sensors in a direction orthogonal to a moving direction of an endless belt and transferred onto the endless belt. Detection of the alignment mark by the alignment sensors and detection of the density adjustment mark by the density adjustment sensor can be performed in parallel.
