Abstract

An image forming apparatus which may include a forming unit configured to form a mark for image adjustment, a conveyor member configured to convey the mark formed by the forming unit and a detecting unit configured to detect the mark conveyed by the conveyor member. Further, the image forming apparatus may include a removing unit configured to remove the mark conveyed by the conveyor member, from the conveyor member; and a control device. According to aspects of the disclosure, after the forming unit has formed a mark for image adjustment, the control device may be configured to determine whether the mark has been removed from the conveyor member and based on the determination of whether the mark has been removed from the conveyor member, begin printing of print data even when the mark has not been completely removed from the conveyor member.

Description

technical field [0001] The present invention relates to an image forming apparatus. More specifically, it relates to an image forming apparatus having a function of forming a mark for image adjustment on a transport body and performing image adjustment based on a measurement result of the mark. Background technique [0002] Conventionally, an image forming apparatus performs image adjustment so that the position and density of an image do not vary. Regarding the steps of image adjustment, for example, on a conveying body such as a paper conveyor belt, a mark for adjusting the positional deviation, that is, a positioning pattern is formed for each color, and the amount of deviation between the positioning pattern of the basic color and the positioning pattern of the color to be checked is obtained. The correction value specified by the deviation is used to correct the positional deviation of the image of the detected color. [0003] For example, Patent Document 1 discloses ...
