Image forming apparatus acquiring image processing time detected when the acquired time is longer that the previously set time and to correct output image density using generated patch pattern

Abstract

An apparatus includes: a transfer unit configured to transfer recording agent onto a transfer sheet to print input data; an acquisition unit configured to acquire, when the transfer unit transfers and when it is detected that processing is to be performed due to which time is extended that is taken from ending processing on the transfer sheet to starting the processing on a following transfer sheet, the time generated due to performance of the detected processing; a generation unit configured to generate, when the acquired time is longer than a previously set time, a patch pattern on the transfer sheet; and a correction unit configured to correct output image density using the generated patch pattern.

Dependencies are inferred from the claim text.
