Abstract
An image forming apparatus including an image carrying member, a detecting section, and a linear-speed deriving section. The image carrying member carries a toner image. The detecting section detects passages of a mark, provided on the image carrying member, at a plurality of predetermined detection positions. The linear-speed deriving section determines a linear speed of the image carrying member from times at which the detecting section detects the passage of the mark.
