Patent number: 8430392Abstract: In order to provide a sheet conveying apparatus and an image forming apparatus capable of alleviating a bumping noise generated between a sheet and an inner guide member when the sheet passes through a curved sheet conveying path, a pair of intermediate conveying rollers is arranged in positions corresponding to both lateral sides in a width direction of the feeding roller and subsidiary feeding roller in a sheet conveyance direction. In addition, the subsidiary intermediate conveying roller abuts on the intermediate conveying roller with an inclination such that the sheet conveyance force is directed to the center of the sheet conveying path in a width direction. As a result, the sheet makes contact with the inner guide member of the facing guide member of the sheet conveying path by undulating the sheet in a width direction when the sheet is extracted and conveyed by the pair of intermediate conveying rollers.Type: GrantFiled: March 16, 2012Date of Patent: April 30, 2013Assignee: Canon Kabushiki KaishaInventors: Takao Nada, Atsushi Kawarago, Taku Nishikawa
