1. A sheet conveying device provided in an image forming apparatus, the image forming apparatus having an image forming portion that forms an image on a sheet-shaped recording material and a heating portion that heats the recording material, the sheet conveying device comprising:
a conveying portion configured to convey the recording material; and
an injection-molded first conveying guide, the first conveying guide forming a conveying path, through which the recording material passes, above the heating portion and having (i) a curved portion for forming a curved path in at least a part of the conveying path and (ii) a plurality of ribs provided on a surface of the curved portion configured to face and contact the recording material, wherein each of the plurality of ribs extends along a conveying direction of the recording material, and the plurality of ribs includes a first rib and a second rib adjacent to the first rib,
wherein the second rib is arranged to be deviated from the first rib in a width direction orthogonal to the conveying direction and in the conveying direction, so as to be spaced apart from the first rib, and
wherein, in the conveying direction, the first rib has a first upstream end and a first downstream end and the second rib has a second upstream end and a second downstream end, the second upstream end being positioned between the first upstream end and the first downstream end, the first downstream end being positioned between the second upstream end and the second downstream end.
