发明名称 IMAGE FORMING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a means for preventing reduction of the nip pressure in a central part in the roller axial direction due to bend of a pushing roller and for preventing reduction of the nip pressure due to engagement of gears of a feeding roller with gears of the pushing roller in a resist roller pair formed of the feeding roller and the pushing roller. <P>SOLUTION: In this image forming device 1, the feeding roller 17 and the pushing roller 18 are structured so that both ends of the feeding roller 17 in the roller axial direction are energized toward the pushing roller 18 to work as a resist roller pair 5 brought in pressure-contact with each other, and this resist roller pair 5 feeds the recording papers P to an image transferring position 10 by correcting bias feed of the recording papers P. The pushing roller 18 is formed into a crown-shape, of which diameter is reduced as it comes from a central part in the roller axial direction toward both ends in the roller axial direction, and one end of the feeding roller 17 in the roller axial direction on a driving gear 21 side is strongly energized toward the pushing roller 18 by the other end thereof in the roller axial direction. <P>COPYRIGHT: (C)2007,JPO&INPIT
