Claims

[Claims for Utility Model Registration] A paper feed tray that can be raised and lowered, and a pair of side fences that are fixed at positions according to the size of paper stacked on the paper feed tray and that regulate both sides of the paper. In a large-volume paper feeder of an image forming apparatus, opposing inner surfaces of the pair of side fences above the uppermost limit of sheets stacked on the paper feed tray at the lowered position of the paper feed tray are connected to both sides of the paper. Formed as a regulating surface that regulates the edge with a regular width,
A large-volume sheet feeding device for an image forming apparatus, characterized in that opposing inner surfaces of the pair of side fences below the regulating surface are formed such that the interval therebetween is wider than the regular width.
