Abstract:
1. An image forming apparatus comprising: an image bearing member configured to carry an electrostatic latent image; a developer bearing member configured to carry a two-component developer including a toner and a carrier, and develop the electrostatic latent image on the image bearing member into a toner image; and a controller configured to selectively perform a first mode in which the developer bearing member rotates at a first peripheral speed during an operation of developing an electrostatic image and a second mode in which the developer bearing member rotates at a second peripheral speed lower than the first peripheral speed during an operation of developing an electrostatic image, wherein in a case that the controller performs the second mode from a status that the image bearing member is stopped, the controller sets a peripheral speed of the developer bearing member to a third peripheral speed which is greater than the second peripheral speed before performing the second mode.
