Publication number: 20070064081Abstract: To provide an image forming apparatus suppressing color slippage without using a mirror with high flatness, when a reflective surface of the mirror used in an optical system of, for example, yellow is formed in a completely flat surface, and a curvature R of the reflective surface of the mirror used in the optical system of magenta is +75 m, a deviation of a scanning position exceeds 100 ?m at maximum, resulting in accentuating the color slippage. Meanwhile, when the mirror of yellow is replaced with the mirror having the curvature R of +300m, the slippage can be suppressed to 100 ?m or less. Therefore, each mirror is selected, so that the curvature of each mirror becomes all positive or all negative. Thus, the deviation of the scanning position is in the same direction of laser beams L of each color, and the slippage can be prevented.Type: ApplicationFiled: September 15, 2006Publication date: March 22, 2007Applicant: Brother Kogyo Kabushiki KaishaInventor: Hitoshi Fujino

Publication number: 20070064082Abstract: An image forming unit is provided in which, through making a distance limiting member to limit a distance between an exposing unit and an image carrying body be able to contact and separate with respect to the image carrying body by a contact/separation enabling section, it is eliminated that developer remaining on the surface of the image carrying body coagulates on the distance limiting member, so it is eliminated that the surface of the image carrying body is scraped by the developer, and that a bad print occurs. The image forming unit has an image carrying body exposed by an exposing unit, a distance limiting member to limit a distance between the exposing unit and the image carrying body. The distance limiting member is installed capable of contacting with and separating from the image carrying body by a contact/separation enabling section.Type: ApplicationFiled: August 31, 2006Publication date: March 22, 2007Applicant: OKI DATA CORPORATIONInventor: Ken Nozawa

Publication number: 20070064083Abstract: A method estimates the temperature of a thermal print head element during printing. In one embodiment, the temperature is estimated using the resistance of the thermal print head element, which typically changes with the print head element temperature. The change in resistance of the print head element is exploited to indirectly estimate the temperature of the print head element.Type: ApplicationFiled: September 20, 2006Publication date: March 22, 2007Inventors: Suhail Saquib, Brian Busch

Publication number: 20070064084Abstract: An image is formed by thermally transferring dyes of a thermal transfer sheet onto a print recording medium, and then a protection layer is formed on the formed image. The transport speed of the print recording medium in the event of thermal transferring the dyes onto the print recording medium is set higher than that in the event of thermal transferring the protection layer onto the print recording medium. Thereby, the amount of thermal energy for application in the event of protection layer formation is increased to be greater than that in the event of image formation. Thereby, occurrence of concave-convex portions formed on the printed surface in association with a density difference in the event of image formation is prevented, and concurrently, the surface pattern in the event of image protection layer formation is improved.Type: ApplicationFiled: September 13, 2006Publication date: March 22, 2007Inventors: Hiroshi Kikuchi, Masahide Maruyama, Yumi Kawamoto, Masanobu Hida
