Claims

[Scope of Claim for Utility Model Registration] (1) Using a paper feeding unit to send paper from a paper storage unit to an image transfer unit for an image carrier, etc., the paper is sent out via a paper conveyance path, and the information of the input image is transferred. The recording paper is formed by an operation such as transferring, and each of the paper storage means is provided in multiple stages, and the paper is fed from each paper storage means to a paper feeding path. In the apparatus, the paper sent out from each of the paper storage means is
A paper feed path for conveying toward an image transfer section is composed of a fixed chute member on the paper feed device side, and an inner chute and an outer chute that can be opened and closed with respect to the fixed chute member, and in the paper feed path, A paper feeding device for an image forming apparatus, characterized in that each of the chute members is configured to be able to be opened and closed during jam processing. (2) Registration of a utility model characterized in that the inner chute and the outer chute constituting the paper feed path can be integrally separated from the fixed chute, and the inner chute is provided so as to be swingable with respect to the outer chute. A paper feeding device for an image forming apparatus according to claim 1. (3) A paper transport path is connected to the paper feed path from an intermediate paper feed tray, and is configured to be able to transport single-sided copied paper for multiplex/double-sided copying from the intermediate tray to the paper feed path, and the paper feed path A paper feeder for an image forming apparatus, characterized in that a part of a guide plate from an intermediate tray is connected to an outer chute constituting the outer chute so that both members can be opened and closed as one unit. (4) The upper frame of the image forming apparatus main body is swingable relative to the lower frame, and a paper feed path from the manual feed tray is formed in the area between the upper and lower frames, and an ejection path at the top of the paper tray. and a guide member that defines the paper feed path from the manual feed tray, and the guide member is configured to be able to swing in conjunction with opening and closing of the upper frame, and by opening the upper frame. A paper feeder for an image forming apparatus, characterized in that the paper feeder is configured such that an ejection path from the uppermost paper tray can be opened.
