Abstract
An image forming apparatus includes a developer container for containing a developer, a developer amount detector for detecting the amount of the developer contained in the developer container, a correcting device for correcting the detected value detected by the developer amount detector, and a memory. At least the developer container and the memory are disposed in a unit and the unit is detachably mountable on a main assembly of the image forming apparatus. The memory stores information indicating that the unit is new. The correcting device corrects a next detected value to be detected by the developer amount detector according to the detected value detected by the developer amount detector when the developer amount detector detects information indicating that the unit is new.
