    摘要: An image forming apparatus includes a forming unit, a storage unit, a correction unit, a measurement unit, and a changing unit. The forming unit forms an image. The storage unit stores correction data for correcting density irregularity in each of a plurality of regions obtained through division in a main scanning direction of the image formed by the forming unit. The correction unit corrects a density of the image formed by the forming unit for each of the plurality of regions based on the correction data stored in the storage unit. The measurement unit measures an image formation density by the forming unit in association with the correction by the correction unit. The changing unit changes the image formation density by the forming unit with a uniform change amount in the plurality of regions so that the image formation density measured by the measurement unit approaches a predetermined target density.

    摘要: An image forming apparatus includes a setting unit configured to set a partition region for dividing a rolled print medium into a plurality of rolls, the partition region being set within a group of images that are sequentially printed accompanying feeding from a feeding apparatus in which the rolled print medium is set; and a printing unit configured to print, on the print medium fed from the feeding apparatus, the group of images reflecting the partition region set by the setting unit. The printing unit prints, on the partition region, an identification image indicating a cutting position for dividing into the plurality of rolls, and the setting unit sets a position at which the identification image is printed, based on information of the group of images.
