Abstract
An image formation system includes: a first image forming apparatus; a sheet inversion section; a second image forming apparatus; an image density detection section configured to detect a density of a first pattern image for a highest density adjustment and a density of a second pattern image for a half-tone density adjustment, each of the first and second pattern images being formed on a sheet in each of the first image forming apparatus and the second image forming apparatus; and an inter-apparatus density adjusting section. The inter-apparatus density adjusting section corrects a density control point and a light exposure energy on a basis of detection results of the first and second pattern images of the image density detection section, respectively. The first and second density control sections correct the density control point or the light exposure energy in accordance with a coverage rate of an image.
