Sheet conveying device and image forming apparatus

A sheet conveying device comprising:

• a sheet conveying passage including
• a first sheet conveying passage through which a sheet on which an image has been formed is conveyed and a second sheet conveying passage which branches from a branch portion in the first sheet conveying passage and through which the sheet is conveyed;
• and
• a switching guide which is disposed at the branch portion, which is swingable about a rotation axis that extends in a sheet width direction perpendicular to a sheet conveying direction, and which switches the sheet conveying passage between the first and second sheet conveying passages,
• wherein
• the switching guide includes
• a supporting portion that extends in the sheet width direction,
• a plurality of guide ribs which are disposed on the supporting portion at intervals in the sheet width direction and which extend along the sheet conveying direction, and
• guide members which are fitted to specific guide ribs that have been selected from the plurality of guide ribs,
• the plurality of guide ribs have
• first guide surfaces that guide the sheet to the first sheet conveying passage, and
• second guide surfaces that guide the sheet to the second sheet conveying passage, and
• the guide members include third guide surfaces formed of a material having higher slidability than the plurality of guide ribs and are disposed at positions protruding further to an inner side of the sheet conveying passage than the first or second guide surfaces.
