Publication number: US20180348680A1
Application number: 15/969,912

Abstract:
A fixing device includes a fixing rotator, a plurality of heat sources having different heat distributions to heat the fixing rotator, a pressing member to press the fixing rotator and form a nip to fix the unfixed toner image on the recording material, a shield disposed between the plurality of heat sources, a plurality of temperature sensors each disposed opposite to the heat source, a processor to control the plurality of heat sources so that a temperature detected by the temperature sensor becomes a predetermined target temperature. The processor controls the heaters so that a temperature difference ΔT=T2−T1 becomes greater than zero, wherein T1 is the target temperature for the temperature sensor close to an entrance of the nip, and T2 is the target temperature for the temperature sensor far from the entrance of the nip.

Publication number: US20180257173A1
Application number: 15/870,490

Abstract:
An optical processing apparatus includes a light source, a condensing optical system, and a shaping optical system. The light source emits light. The condensing optical system condenses the light emitted from the light source onto a processing target position on a surface of an object to be processed. The shaping optical system shapes a spot shape of the condensed light, such that a ratio of a major axis diameter of the spot shape to a minor axis diameter of the spot shape, in a cross section orthogonal to an optical axis of the condensed light on the object to be processed, is a minimum at or adjacent to a focal position of the shaping optical system. A method for optically processing an object is also provided.
