摘要： A separation device separates a recording medium ejected from a fixing nip formed between a first rotator and a second rotator from the first rotator. The separation device includes a separator including a front end disposed opposite the fixing nip and the recording medium and a plurality of recesses disposed on the front end of the separator at least in a conveyance span on the separator where the recording medium is conveyed. The plurality of recesses includes a first recess extending in a first extension line that is oblique relative to a recording medium conveyance direction and a second recess adjacent to the first recess and extending in a second extension line that is oblique relative to the recording medium conveyance direction. The second extension line overlaps the first extension line in a direction perpendicular to the recording medium conveyance direction to define an overlap span.

摘要： A separation device includes an endless belt, a rotary body, a separation supporter, and a transfer mechanism. The separation supporter presses against an inner circumferential surface of the endless belt downstream from an area of contact between the endless belt and the rotary body in a recording medium conveyance direction to curve the endless belt toward an outer circumferential surface side of the endless belt at a greater curvature than a curvature of the endless belt at the area of contact between the endless belt and the rotary body. The transfer mechanism switches the separation supporter between a first position and a second position farther from the area of contact between the endless belt and the rotary body than the first position.
