A device comprising a conveying means formed by stretching a conveying belt around a belt roller, and an original ejecting means driven by a drive means separate from the conveying means, and which is capable of forming an image. In a document feeding device configured to simultaneously convey a preceding document that has undergone exposure processing by the device and a subsequent document that has been kept on standby upstream of the preceding document, the document is By controlling the feeding timing of the preceding original, when the preceding original is moved together with the next original due to the completion of exposure processing, the leading edge of the preceding original is always nipped by the original ejecting means, and the exposure processing of the next original is nipped. In particular, in order to cause the document ejecting device to continue ejecting the preceding document, the document ejecting device may include a control device for controlling the distance between the trailing edge of the preceding document and the leading edge of the next document. Characteristic document feeding device. 2. The document feeding device according to claim 1, wherein the document feeding timing is controlled by registration rollers that temporarily lock the leading edge of the document on the upstream side of the conveyance means.
