A sheet conveying apparatus which conveys a sheet includes: a first rotating member made of a material which is positive with respect to the sheet in a triboelectric series; and a second rotating member made of a material which is negative with respect to the sheet in the triboelectric series, wherein the first and second rotating members are arranged in a conveyance direction of the sheet and arranged to be contact with the same surface of the sheet, and a foreign material is removed from the conveyed sheet by the first and second rotating members.

A print media discharge unit includes a print media transport path along which in operation a sheet of print media is transported in a transport direction. The print media transport path is defined by a first electrically isolating print media guide and a second electrically isolating print media guide. The print media discharge unit further includes an electrically grounded electrically conductive discharge element extending through an opening in at least one of the first and second electrically isolating print media guides into the print media transport path. At least one of the first and second electrically isolating print media guide includes a plurality of guidance ribs aligned substantially in the transport direction at an angle with respect to the transport direction.
