Image forming system including an image reading unit in a paper conveying path downstream from an image forming unit

摘要

Disclosed is an image forming system, including: a conveying unit configured to convey recording paper; an image forming unit configured to print an image on the recording paper; an image reading unit configured to optically read the recording paper and to obtain a read image; and a correction control unit configured to control an execution of a test operation in which a test pattern including one or more thin lines are printed on the recording paper by the image forming unit and in which the test pattern is read by the image reading unit, to collect information indicting operation state of each unit in the execution of the test operation, to evaluate the thin lines in the read image obtained in the test operation in consideration of the collected information and to carry out a correction relating to printing of a specified thin line.
