Abstract
A one piece, low cost, self-loading, articulating and hard surfaced idler roll is provided for use in a xerographic copying machine or the like. The idler roll includes an outer core with a surface of sufficient hardness to be non-compliant when sheet material and a drive roll comes into contact with it. A compliant material is positioned between a shaft which can be hollow and the outer core in order to complete the one piece structure and allow the idler roll to articulate about the shaft to diminish skewed entry of sheets into the nip formed between the idler roll and the drive roll.
