Patent ID: 8582128

Claim:
An image-formation control device configured to control an image forming apparatus configured to perform image formation on a continuous form that has side portions provided with holes and that has a page boundary per predetermined length, the image-formation control device comprising: an input receiving unit configured to receive an input of a displacement of an image forming area in a sub-scanning direction from a reference position on the continuous form, the image forming area being a target of the image formation; a marker-length calculating unit configured to calculate marker lengths of an upper marker marking an upper end of a page of the continuous form and a lower marker marking a lower end of a page of the continuous form, based on the displacement, a shortest distance to the holes from the page boundary in the side portions, and a reference marker length for when the displacement is not specified with respect to each of the upper marker and the lower marker; a marker-start-position calculating unit configured to calculate image-formation start positions of the upper marker and the lower marker based on the displacement, the distance, the reference marker length, and a length of the image forming area in the sub-scanning direction; and a control unit configured to perform, with respect to the image forming apparatus, control of the image formation of the upper marker and the lower marker in the side portions from the image-formation start positions calculated over the marker lengths calculated.
