# Document transport device including stopper for prevention of falling of document and image forming apparatus

## Abstract

A document transport device includes an ejection tray on which documents ejected in a predetermined ejection direction are loaded and a stopper that prevents documents from falling from the ejection tray in the ejection direction. The stopper has a rotating shaft rotatably supported at the ejection tray in a direction intersecting the ejection direction, a contact piece provided at the rotating shaft to be hit by a tip of a document in the ejection direction, and a weight piece provided at the rotating shaft. The stopper is able to pivot to be in a standing posture in which the contact piece stands due to the weight of the weight piece and pivot to be in a tilting posture in which the stopper tilts in the ejection direction from the standing posture when a predetermined force is applied to the contact piece.
