Abstract
In a fixing device, a first reflection plate covers a part of an outer circumferential surface of an infrared heater in a circumferential direction of the infrared heater along an axial direction of the infrared heater substantially perpendicular to the circumferential direction of the infrared heater. The first reflection plate reflects light emitted by the infrared heater toward a fixing member. At least one light control mirror is provided in at least one end of the first reflection plate in an axial direction of the first reflection plate. At least one second reflection plate opposes the infrared heater via the at least one light control mirror to reflect the light emitted by the infrared heater and passing through the at least one light control mirror toward a center portion of the fixing member in an axial direction of the fixing member.
