Separation device, fixing device, and image forming apparatus

A fixing device comprising:

• a first rotary body;
• a second rotary body contacting the first rotary body;
• and
• a separation device disposed downstream from the first rotary body and the second rotary body in a recording medium conveyance direction in which a recording medium is conveyed between the first rotary body and the second rotary body,
• the separation device including at least one separator disposed opposite one of the first rotary body and the second rotary body,
• each of the at least one separator including:
• a front aligned in an axial direction of the one of the first rotary body and the second rotary body and including a recording medium conveyance face over which the recording medium slides, the recording medium conveyance face including a front edge produced with a burr extending from a surface of the at least one separator having a height not greater than about 25 micrometers;
• and
• a recess produced on the recording medium conveyance face and extending in a direction perpendicular to the recording medium conveyance direction,
• wherein the recording medium conveyance face has a surface roughness defined by one of an arithmetic average roughness not greater than about 1.5 micrometers, a maximum height not greater than about 10.0 micrometers, and a ten point average roughness not greater than about 7.2 micrometers.
