Abstract
An image forming apparatus includes an image forming portion for forming an image on a recording material, a sensor to detect a toner image formed by the image forming portion, and a correcting portion to correct an image forming condition of the image forming portion on the basis of a result of detection, by the sensor, of a first control toner image formed by the image forming portion. In addition, a supply controller controls a developer supplying operation on the basis of a result of detection, by the sensor, of a second control toner image formed by the image forming portion. A controller controls an image forming condition such that the first control toner image is formed at the image forming speed of a second image forming mode, and the second control toner image is formed after the image forming speed is changed to a third image forming speed which is higher than the second image forming speed.
