ABSTRACT:
The present invention is to provide a paper stacker for use with an image forming apparatus of a high copying speed. The paper stacker comprises a paper conveying means for conveying a paper with an image recorded thereon to a stacking position, a top end stopper provided reciprocatively movably along a conveying path of the paper, a paper receiving plate disposed below the conveying path of the paper for receiving a paper, a rear end stopper for defining the rear end position of the paper on the paper receiving plate, and an elevating device for changing the height of the paper receiving plate, wherein the top end stopper and the rear end stopper are provided movably in the same direction in the conveyance direction per a given number of papers. The papers are stacked only by shifting the top end stopper and the rear end stopper in the conveyance direction so that the stacker configuration is extremely simplified so as to enable a high speed.
