摘要： PROBLEM TO BE SOLVED: To provide an automatic document feeder which is provided with excellent stacking property, and to provide an image forming apparatus employing the same.
SOLUTION: In the automatic document feeder which separately feeds documents one by one from a loaded document bundle 1, when a quantity of documents are simultaneously processed, ejection conditions from the first document to the final document become considerably different in the document bundle 1 and stacking property of the ejected document bundle is made worse. Therefore, a rising distance L of a movable document table 3 is calculated from the total number of pulses required for rising drive control of the movable document table 3, an estimated height of ejected documents 1a on an ejection tray 29a that is made movable by being vertically turned by a motor or the like, is derived, ejection speed control is performed, and deceleration processing for decreasing the amount of ejected paper is carried out. When removal of the ejected documents 1a is confirmed by a left paper sensor 29b provided in the ejection tray 29a, the ejection tray 29a is returned to a home position at which the amount of ejected paper is zero, and the estimated height of the ejected documents 1a is reset, thereby stacking documents again from zero.
