Abstract
A fixing device includes a separator disposed downstream from a fixing nip formed between a fixing rotary body and a pressing rotary body in a recording medium conveyance direction to separate a recording medium from the fixing rotary body. The separator includes a front disposed opposite an outer circumferential surface of the fixing rotary body with a given interval therebetween and a conveyance face contiguous to the front, over which the recording medium slides. A coating layer, made of fluoroplastic, coats the front and the conveyance face of the separator. The coating layer includes a front portion corresponding to the front of the separator and produced with a plurality of recesses extending in a width direction of the separator orthogonal to the recording medium conveyance direction throughout substantially an entire width of the separator in the width direction thereof.
