Abstract
An image forming apparatus is capable of performing a first image forming mode that performs image formation at a first peripheral speed ratio representing a ratio of a peripheral speed of a developer bearing member to a peripheral speed of an image bearing member and at a second image forming mode that performs the image formation at a second peripheral speed ratio different from the first peripheral speed ratio. The image forming apparatus also detects an amount of a developer consumed in the image formation, based on an estimate of the amount of the developer consumed by one pixel and the number of pixels at a part at which the developer is consumed. The estimate of the amount of the developer consumed by the one pixel in the first image forming mode is different from that in the second image forming mode.
