摘要： An image forming apparatus capable of collectively and accurately detecting the remaining sheet amount of sheets set in sheet feed trays. The remaining sheet amount value of each sheet feed tray is detected in stepwise levels. Whenever sheet feed is detected, the remaining sheet count is decremented by 1. Upon detection of a change in the remaining sheet amount value, the changed remaining sheet amount value is acquired, and the remaining sheet count is changed to the changed remaining sheet amount value. If the sheet feed trays include any other one set to the same type and size of sheets as those of sheets to which the sheet feed tray in current use is set, when the remaining sheet count of the sheet feed tray in current use is changed to the changed remaining sheet amount value, the other sheet feed tray is selected for feeding sheets.
