    摘要: An image forming apparatus capable of controlling density of an output image with high accuracy regardless of variation of internal temperature. A controller controls an image forming unit to form a measurement image, controls a light receiving unit to receive reflected light from the measurement image, controls a conversion unit to convert an output value of the light receiving unit, and controls an image formation condition based on a value that is obtained by converting the output value. An adjustment unit controls the light receiving unit to receive reflected light from an image bearing member, and adjusts the emission light amount of an emission unit based on the reflected light from the image bearing member. A selection unit selects a conversion condition from among conversion conditions based on a reference temperature that is detected when the adjustment unit adjusts the emission light amount and a current temperature.

    摘要: In an image forming apparatus, a heating member for heating a recording sheet and a pressuring member disposed below the heating member are supported by a fixing unit frame. A noncontact temperature sensor disposed facing the heating member detects a temperature of the heating member without contacting the heating member. An upper frame covers an upper portion of the heating member and an upstream portion of the heating member in a conveying direction of the recording sheet. A plate-shaped upper sheet guide protrudes upstream in the conveying direction from an upstream end of the upper frame and extends in a width direction perpendicular to the conveying direction and to a vertical direction. The upper sheet guide and a lower sheet guide disposed below and facing the upper sheet guide the recording sheet in the conveying direction toward the heating member and the pressuring member.
