IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing stock failure of a sheet on a paper discharge tray.SOLUTION: A sheet discharge part 20 of an image forming apparatus comprises a drive roller 30 and a driven roller 40 for holding a sheet from above and below. The drive roller 30 comprises: a drive rotation shaft 31; a driver roller 32 provided at the center part of the drive rotation shaft 31; and rotors 33 supported rotatably to both end parts of the drive rotation shaft 31 and having an external diameter larger than the drive roller 32. The driven roller 40 is disposed above the drive roller 30 while facing the drive roller 30 and comprises: a driven rotation shaft 41; a driven roller 42 provided at the center part of the driven rotation shaft 41 and driven by the drive roller 32 of the drive roller 30; and outer roller parts 43 having an external diameter smaller than the driven roller 42 and provided on both sides of the driven roller 42. The outer roller parts 43 are formed so that the external diameter becomes smaller toward both ends from the center of the driven rotation shaft 41.
