PROBLEM TO BE SOLVED: To provide a paper feeding device that can maintain horizontally a posture of an envelope at the highest position of envelopes stored with a simple structure and an image forming system.SOLUTION: The paper feeding device comprises a placing surface part 321, a paper feeding roller 313, a pressing surface part 362 and a curve forming part 363. A length of the placing surface part 321 in a width direction is set shorter than an envelope P. The pressing surface part 362 is pressed against the paper feeding roller 313 through the envelope P. The curve forming part 363 is provided more outside than the paper feeding roller 313 in the width direction, and protruded upward in a vertical direction more than the pressing surface part 362, so as to support a plurality of placed envelopes P of a predetermined size.SELECTED DRAWING: Figure 2 |
