A cooling device used in an electrophotographic image forming device includes a cooling roller, which is a heat roller, and a backup roller pressed against the cooling roller to form a nip portion therebetween. Straight-line ribs higher than the light emitting members are formed on the second substrate with one of the lines of light emitting members interposed between each adjacent pair of ribs. Then, a vibration of the synthesized image capturing data is corrected based on a divide pattern indicating divisions, and the motion amount. The cartridge is rotatably mounted in the housing such that an outlet in the cartridge is movable with respect to the bore in the housing between maximum fluid flow, intermediate fluid flow, and fluid flow blocking positions. A rotator rotates around a rotation shaft fixed to the cylindrical main body case, and is coupled with a coupling portion of the needle holder on a first one of two sides of the rotator with the rotation shaft interposed therebetween and is coupled with the second elastic object on a second one of the two sides of the rotator. Also disclosed is a method for using the device.
