摘要： In an overfilled optical scanner in which a plurality of light beams are used, a uniform luminous-energy distribution is achieved on a scanning plane to be scanned. The optical scanner includes: a light source 3 for producing a first light beam L1 and a second light beam L2; a polygon mirror; a first image formation optical system for leading the light beams L1 and L2 to a deflecting plane of the polygon mirror and for forming, on the deflecting plane, a line image whose width is greater than the plane width of the deflecting plane; and a second image formation optical system for leading the light beams L1 and L2 from the polygon mirror to the scanning plane of a photosensitive drum and forming an image on the scanning plane. The first image formation optical system is adjusted so that the optical axes A1 and A2 of the first and second light beams L1 and L2 are approximately symmetrical about the optical axis A0 of the first image formation optical system. The powers of the first and second light beams L1 and L2 are thus balanced with each other on the scanning plane.

The reflector 10 includes a thin-plate-shaped reflector body having one plane to be a reflection plane 20 and upper and lower ribs 21a and 21b each extending from the reflector body in a back side. The reflector plane 20 is formed of a curved plane having positive power at least in the scanning direction, i.e., a so called free-form plane. The reflector 10 is supported by protrusions 31, 32 and 33 at three points, i.e., first, second and third support points S1, S2 and S3 located in the vicinities of one end portion of the reflector, the other end of thereof, and a center portion thereof, respectively. A distance L1 between an imaginary straight line V1 joining the first and second support points S1 and S2 and the third support point S3 is larger than a sag L2 of the reflector 20. The center of gravity G of the reflector is located inside of an imaginary triangle V3 joining the first, second and third support points S1, S2 and S3.

摘要： A heating roller (21) includes a heat generating layer (22) that generates heat by electromagnetic induction, a heat insulating layer (23), and a supporting layer (24), which are provided inwardly in this order. The supporting layer (24) is formed of a material having a specific resistance of 1×10−5 Ωm or higher. Therefore, even when the heat generating layer (22) has a thickness smaller than a skin depth, i.e. a thickness defined by a flow of an induction current, so that magnetic flux penetrates the heat generating layer (22) and even reaches the supporting layer (24), heat generation of the supporting layer (24) under an eddy current can be suppressed. Thus, the heat generating layer (22) can be decreased in thermal capacity, and heat generation of the supporting layer (24) is suppressed, so that only the heat generating layer (22) can be heated efficiently. As a result, a warm-up time can be reduced. Further, breakage by heat of, for example, bearings supporting the heating roller (21) can be prevented.

摘要： A heating roller (21) includes a heat generating layer (22) that generates heat by electromagnetic induction, a heat insulating layer (23), and a supporting layer (24), which are provided inwardly in this order. The heat generating layer (22) is composed of at least two layers that are a first heat generating layer of a magnetic material and a second heat generating layer of a non-magnetic material. The first heat generating layer has a specific resistance higher than a specific resistance of the second heat generating layer and a thickness larger than a thickness of the second heat generating layer. This allows the second heat generating layer to function effectively as a heat generating part that generates heat by electromagnetic induction. Thus, compared with the case where the heat generating layer (22) is formed only of a single layer of a magnetic material, heat generation efficiency is increased, thereby allowing warm-up time to be reduced. Further, the heat generating layer (22) is heated intensively, so that heat generation of the supporting layer (24) is reduced, thereby allowing the prevention of breakage of, for example, bearings supporting the heating roller (21).

摘要： A temperature determining device is composed of a temperature detecting unit that detects a temperature of a determination object member based on an intensity of infrared rays from the object member, a unit for determining a temperature for correction that determines a temperature of an opposing member opposed to the object member or a temperature of a member whose temperature changes in correlation to a change in the temperature of the opposing member, and a calculating unit that corrects the detected temperature obtained by the temperature detecting unit using the temperature as the temperature for correction obtained by the unit for determining a temperature for correction. Thus, stable temperature determination can be performed accurately without being influenced by infrared rays from around a determination object member.

摘要： A circuit breaker for a double-break mechanism includes a current interrupting section having a contact mechanism. The contact mechanism includes first and second fixed contactors arranged in parallel and having fixed contacts, and a bridging movable contactor having an arm with movable contacts opposing the fixed contacts. A magnetic plate may be interposed in a middle region between two pairs of the fixed and movable contacts extending along a path of switching movement of the movable contactor. Partition walls formed of organic polymer material may be provided to stand along the path of the movable contactor. The partition walls sandwich each pair of the fixed contact and the movable contact to form a narrow gap arc extinguishing space between the partition walls.
