Claim:
1. An image forming apparatus comprising: a printing section; and a control unit, wherein the control unit implements: an acceptance section configured to accept an instruction for the printing section to change a printing speed; and an operation control section configured to control an operation of the printing section, wherein when the acceptance section accepts the instruction to change the printing speed, the operation control section calculates a first amount of time to be taken from when the printing section starts printing at a printing speed before being changed until the printing section completes the printing, a second amount of time to be taken from when the printing section starts the printing at a changed printing speed until the printing section completes the printing, and a third amount of time to be taken for the printing section to change the printing speed and start the printing at the changed printing speed, compares a total amount of time of the second and third amounts of time with the first amount of time, and determines whether to allow the printing section to change the printing speed based on a result of the comparison, wherein the printing section selectively changes the printing speed based on the determination.
