ABSTRACT:
A paper-supplying device in an image-forming apparatus includes a paper-supplying portion to be charged with a paper-housing vessel by moving the latter in a direction of a rotary axis of a shaft of a paper-supplying roller. The vessel is provided with paper-separating clicks for pressing paper at opposite corners thereof on a downstream side thereof in a paper-supplying direction of the paper and an energizing structure for lifting a carrier plate supporting the paper thereon upwardly toward the paper-separating clicks. The roller is movable in the direction of the rotary axis of the shaft thereof. Transfer structure lifts the vessel in an upwardly inclined direction to press the paper against the roller when the paper-supplying portion is charged with the vessel. A member, brought into contact with the vessel before a surface of the paper is brought into contact with the roller and moved in the direction of charging the vessel, is connected with the roller in a relatively rotatable manner. Position-returning structure returns the member to an initial position.
