| 摘要 | A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a pressure rotator pressed against an outer circumferential surface of the fixing rotator. A heater is disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. A reflector is disposed opposite the heater to reflect light radiated from the heater onto the inner circumferential surface of the fixing rotator. A support mounts the reflector. A heater holder is mounted on the support to hold the heater. | ||

| 主权项 | 1. A fixing device comprising: a fixing rotator rotatable in a predetermined direction of rotation; a pressure rotator pressed against an outer circumferential surface of the fixing rotator; a heater, disposed opposite an inner circumferential surface of the fixing rotator, to heat the fixing rotator; a reflector, disposed opposite the heater, to reflect light radiated from the heater onto the inner circumferential surface of the fixing rotator; a support mounting the reflector; a heater holder, mounted on the support at a position inboard from a lateral end of the support, to directly contact and hold the heater; and a biasing member to bias the heater against the heater holder, wherein the heater holder includes an abutment portion to abut the heater biased by the biasing member. | ||
