PROBLEM TO BE SOLVED: To achieve suppression in density unevenness of a toner image and suppression in coagulation of a developer.SOLUTION: In an image formation apparatus, a control part causes an exposure part and a development part to form to a photoreceptor the first toner image including a prescribed straight line connecting on a peripheral surface the first point and the second point apart from the first point by the first distance to the upstream side in the conveyance direction of the peripheral surface and apart from the first point by the second distance to the one side in the first direction while controlling the toner conveyance speed to the first conveyance speed, the value of the ratio of the second distance to the first distance is substantially equal to the value of the ratio of the first conveyance speed to the prescribed speed, a first detection part and a second detection part detect the image density of the first toner image at different positions in the first direction, and the control part executes determination processing for determining the toner conveyance speed at the time of formation of the second toner image to a print medium on the basis of the image density detected by the first detection part and the second detection part.SELECTED DRAWING: Figure 3 |
