    摘要： A technique for reducing downtime that accompanies the execution independently of adjustment processing for maintaining image quality and the execution of finishing processing relating to a printing medium. In order to apply the finishing processing to the printing medium in a finishing processing unit, an image forming apparatus to which this technique is applied sets a time between sheets that extends from end of image formation regarding a first sheet of the printing medium to start of image formation regarding a second sheet of the printing medium transported following the first sheet of the printing medium in the image forming unit, and executes adjustment processing, which is for maintaining image quality in the image forming unit, within the set time between sheets.

    摘要： Adjustment processing is suitably executed in accordance with the type of post processing. To accomplish this, an image forming apparatus includes, for example, an adjustment part, specifying part, and control part. The adjustment part performs at least one of adjustment operation for an image formation position and adjustment operation for an image formation density by forming adjustment patterns using a developing material on an image carrier and measuring the adjustment patterns. The specifying part specifies the size of an image to be formed on a sheet and the content of post processing in case of executing a job which requires post processing on the sheet. The control part controls, in accordance with the size of the image and the content of the post processing, whether to perform the adjustment operation by the adjustment part concurrently with the formation of an image made from a job requiring post processing.

    摘要： To detect differences in the main-scanning length of each beam on a photosensitive member, patterns for correction are formed on the photosensitive member using only beams (L1, LN) at both ends among a plurality of beams aligned in a sub-scanning direction. The patterns are transferred onto an intermediate transfer belt and detected with photosensors, a difference ΔLN of scanning length between a 1-st line and a N-th line is calculated, and a difference ΔLi of scanning length of a i-th line is calculated by ΔLi=ΔLN×(i/N−1) so as to proportionally distribute ΔLN to the i-th line. The scanning lengths of lines are respectively corrected to be equal each other using the obtained differences ΔLi of scanning length. Thus, an image forming apparatus and a control method that reduce a decline in image quality, even when scanning incident angles of laser beams onto a photosensitive member differ for each of beams on forming images by scanning a multiple lines with a multiple beams, can be provided.
