Abstract
A separation device, which is located downstream from a transfer roller in the sheet transport direction, applies a separation voltage to a plurality of separation needlesdisposed in an alignment orthogonal to the direction of transport of the sheet, so as to produce a discharge between a photosensitive drumand the separation needlesand to remove the charge on the sheet that was charged by a transfer roller, so as to separate the sheet from the photosensitive drum, the separation devicehaving an upstream walland a downstream wall, and a ground electrodebeing disposed on the back side of the downstream wall, which is the side not facing the separation needles, and protruding towards the photosensitive drum, beyond the line that connects the tips of the separation needlesand the end of the downstream wall
