ることを特徴とする画像形成装置の給紙装置。 On the downstream side in the conveyance direction of the paper feed roller, which is driven to rotate while in contact with the topmost sheet of sheets to be stacked in the paper feed cassette, is a raised position that is spaced from the topmost sheet and comes into contact with the topmost sheet. A friction member is provided that can be raised and lowered freely between the lowered position and the lowered position, and the raised and lowered friction member and the rotational drive of the paper feed roller are controlled such that when the friction member is in the lowered position, the paper feed roller starts rotating;
By associating the friction member to rise while the paper feed roller is rotating, the portion of the topmost paper located between the friction member and the paper feed roller is temporarily curved upward by the paper feeding action of the paper feed roller. In the paper feeding device of the image forming apparatus configured to allow the paper feeding roller and the friction member is configured to be freely bendable around a bent axis substantially parallel to the pivot axis at an intermediate position between the friction member and the friction member;
An image characterized in that a mounting plate portion located upstream in the conveying direction and a mounting plate portion located downstream in the conveying direction from the waist bending axis are individually biased upward by separate springs. Forming device paper feed device.
