Abstract:
Disclosed is an image forming apparatus that 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 a second image forming mode that performs the image formation at a second peripheral speed ratio different from the first peripheral speed ratio, and that 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.

Claim (Index 10):
An image forming apparatus comprising:\n an image bearing member; an exposure unit configured to form an electrostatic latent image on the image bearing member by emitting light to the image bearing member based on image information; a developer bearing member configured to develop the electrostatic latent image with a developer; a control portion; and an alerting device configured to alert an alarm concerning a residual amount of the toner; wherein the control portion makes the alerting device to alert an alarm concerning a residual amount of the toner based on a lighting amount of the exposure unit, wherein the image forming apparatus is capable of operating in a first mode in which the image forming apparatus performs image formation at a first peripheral speed ratio representing a ratio of a peripheral speed of the developer bearing member to a peripheral speed of the image bearing member, and in a second mode in which the image forming apparatus performs image formation at a second peripheral speed ratio, which is greater than the first peripheral speed ratio, wherein the alert by the alerting device accords to a total amount of the lighting amount, the total amount of the lighting amount being smaller as an operation frequency of the second mode becomes higher than an operation frequency of the first mode.
