Abstract
An image forming apparatus performs a scattered toner ejection control mode in which toner is discharged from a developer bearing member to a region on an image bearing member corresponding to an interval between a preceding recording material and a subsequent recording material while applying only a DC voltage to a developer bearing member based on toner consumption information and a degraded toner ejection control mode in which toner is discharged from the developer bearing member to a region on the image bearing member corresponding to an interval between a preceding recording material and a subsequent recording material while applying at least an AC voltage to the developer bearing member based on toner consumption information, the controller changing a performing ratio of the scattered toner ejection control mode to the degraded toner ejection control mode depending on the temperature sensed by a temperature sensing portion.
