PROBLEM TO BE SOLVED: To provide a sheet transport device and an image forming apparatus capable of reducing the reaction force generated by the nip force of transport rollers applied on an opening and closing door which is opened and closed when paper jamming is processed.SOLUTION: Provided is a sheet transport device, which comprises: a device main body on which one roller of a first transport roller pair that transports sheets is provided; an opening and closing door which is movably and rotatably supported between a closing position where a part of a sheet transport path formed on a side surface of the device main body is covered and an opening position where a part of the sheet transport path is open, and on which one roller of a second transport roller pair provided on the sheet transport path is provided; and a transport unit which includes the other roller of the first transport roller pair and the other roller of the second transport roller pair, and is swingably supported by the opening and closing door. When the opening and closing door moves to the closing position from the opening position, the opening and closing door is positioned in a second positioning portion formed on the device main body after the transport unit is positioned in a first positioning portion formed on the device main body. |
