Abstract
A sheet conveyance apparatus includes a guide for the recording sheet formed by a discharging layer. The layer includes an electrically grounded conductive substrate and an organic conductive fiber thereon. The surface of the guide is in close proximity to the surface of the recording sheet.
Claims10
A sheet conveyance apparatus comprising:
- a guide for a recording sheet, having a cylindrically curved surface in close proximity to a surface of the recording sheet, along a convex surface over which recording sheet is guided and, thereafter, from which the recording sheet is separated so as to be reversed, aligned, and then stacked,
- wherein said guide includes a discharging layer having an electrically grounded conductive substrate, an organic conductive fiber on the conductive substrate, and a support provided on the convex surface of the discharging layer, which supports and guides the recording sheet without bringing the recording sheet into contact with the discharging layer, the support being on a same side of said recording sheet as the convex surface of said discharging layer.
A sheet conveyance apparatus of claim 14 wherein the rib has thickness of 2 to 10 mm.
A sheet conveyance method comprising:
- moving a recording sheet toward a discharging layer, which layer includes an electrically grounded organic conductive fiber, so that a cylindrically curved surface of the discharging layer is in close proximity to a surface of the recording sheet;
- supporting the recording sheet by a support provided on a convex surface of the discharging layer, the support being on a same side of the recording sheet as the convex surface of the discharging layer;
- guiding the recording sheet along the support without bringing the recording sheet into contact with the discharging layer,
- separating the recording sheet from the convex surface of the discharging layer so as to be reversed;
- and then
- aligning and stacking the recording sheet.
