Abstract

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.

Claims6

Dependent claims

A sheet conveying apparatus comprising:

a first sheet conveying portion including a rotating member configured to convey a sheet;
a second sheet conveying portion that is arranged on downstream of the first sheet conveying portion, includes a plurality of pairs of rotating members provided in a width direction perpendicular to a sheet conveyance direction, and conveys the sheet from the first sheet conveying portion using the plurality of pairs of the rotating members;
and
a sheet conveying path that includes an outer guide member and an inner guide member facing each other and is curved to guide the sheet conveyed by the second sheet conveying portion to a downstream side,
wherein the plurality of pairs of the rotating members of the second sheet conveying portion are arranged in positions corresponding to both lateral sides in a width direction of the rotating member of the first sheet conveying portion in a sheet conveyance direction when the sheet is conveyed by the second sheet conveying portion, and a sheet conveyance force caused by the plurality of pairs of the rotating members of the second sheet conveying portion is directed to a center of the sheet conveying path in a width direction.
