Claim:
1. An image forming apparatus comprising: a printing section; and a control unit, wherein the control unit implements: an operation control section configured to control an operation of the printing section; a post-processing section configured to perform post-processing of a recording paper sheet subjected to printing by the printing section; and a delay time calculating section configured to calculate a delay time in a printing process to be generated by the post-processing performed by the post-processing section, wherein when the delay time calculated by the delay time calculating section is equal to or longer than a predetermined first time period, the operation control section controls the printing section to perform a printing operation at a predetermined printing speed higher than a normal printing speed, when the operation control section controls the printing section to perform the printing operation at the printing speed higher than the normal printing speed, the delay time calculating section calculates a shortened time in the printing process to be generated by the control and subtracts the shortened time from the delay time, and if a time obtained by subtracting the shortened time from the delay time is equal to or shorter than a predetermined second time period, the operation control section stops controlling the printing section to perform the printing operation at the printing speed higher than the normal printing speed and allows the printing section to perform the printing operation at the normal printing speed.
