Abstract: A sheet conveying device includes a sheet conveying passage and a switching guide. The switching guide switches the sheet conveying passage between first and second sheet conveying passages. The switching guide includes a plurality of guide ribs and guide members. The plurality of guide ribs are disposed at intervals in the sheet width direction and extend in the sheet conveying direction. The guide members are fitted to specific guide ribs selected from the plurality of guide ribs. The plurality of guide ribs have first and second guide surfaces that guide the sheet. The guide members are formed of a material having higher slidability than the plurality of guide ribs, and have third guide surfaces that are disposed at positions protruding further to an inner side of the sheet conveying passage than the first or second guide surfaces.

Abstract: An image formation air blowing device includes an outlet and an airflow control portion. The outlet blows out an airflow toward a target space on a discharge table to which a sheet with an image formed thereon by an image forming portion is discharged. The airflow control portion controls a direction of the airflow at least in a horizontal plane in the target space.
