PROBLEM TO BE SOLVED: To accurately suppress a rotation variation component of a rotating body that rotates to form images.SOLUTION: An image forming apparatus 1000 calculates a speed correction amount in which the gain and phase of a speed variation component is corrected to cancel the speed variation component with a gain and phase correction part and a correction speed calculation part, and controls the rotation speed of a rotating body by using the calculated speed correction amount. |
