Abstract
An image forming apparatus includes sheet bundle boundary detecting unit which detects a boundary of sheet bundles added to a sheet storage case, and control unit which controls a feeding condition of sheet feeding unit based on a detection result of the sheet bundle boundary detecting unit. With this, overlapping-feeding and miss-feeding at the boundary between the sheet bundles are reliably prevented.
