Abstract
An image forming apparatus determines a remaining recording material amount based on a sensor value and a predicted value. When a sensor falsely detects the remaining recording material amount, the image forming apparatus appropriately determines the remaining recording material amount. Upon acquisition of a new sensor value, the image forming apparatus does not update a current value with the new sensor value if a difference between the new sensor value and the current value is a predetermined value or greater.
