PROBLEM TO BE SOLVED: To provide an image forming device having improved feeding accuracy and a reduced number of parts while improving its working efficiency in mounting the parts. SOLUTION: A feeding roller bearing part 6a includes an abutting portion 6c for abutting on the outer face of a bearing mounting portion of a frame 1, an engaging portion 6e for engaging with the inner face of the bearing mounting portion 1g of the frame 1, and a restricting portion 6g for restricting the movement of a feeding roller 2 in the axial direction. A platen roller bearing part 6b formed integrally with the feeding roller bearing part 6a includes an abutting portion 6d for abutting the outer face of a bearing mounting portion 1h of the frame 1 and an engaging portion 6f for engaging with the inner face of the bearing mounting portion 1h of the frame 1. In the state that the abutting portion 6c of the feeding roller bearing part 6a abuts on the outer face of the bearing mounting portion 1g of the frame 1 and the engaging portion 6e thereof engages with the inner face of the bearing mounting portion 1g of the frame 1, the feeding roller bearing part 6a is thrust via a pressing roller 3 and the feeding roller 2 by the thrusting force of a torsion coil spring 15. A portion of the feeding roller bearing part 6a, opposed to the pressing roller 3, is opened. COPYRIGHT: (C)2006,JPO&NCIPI
