Title: Developing roller, developing device, image forming apparatus and developing roller manufacturing method
Inventor: MATSUMOTO DAISUKE
IPC: G03G15/08
Filed: 2008-12-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide: a developing roller capable of coping with the distortion thereof and obtaining appropriate developing characteristics; a developing device; an image forming apparatus using the developing device; and a developing roller manufacturing method.  <P>SOLUTION: The developing roller is characterized in that toner conveying grooves are continuously formed in the surface of a cylindrical member, and the groove depth of each groove is continuously increased as it comes close to each end from the center part in the axial direction. The groove depth is increased as it comes closer to the end part from the center part in the axial direction, then, the toner carrying amount at the center part becomes different from that at the end part. Accordingly, the appropriate developing characteristics are obtained while coping with a change in an electric field strength due to the distortion of the developing roller, using a level difference of an electric field value at which toner-scattering starts, caused due to the difference of the toner conveying amount.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of suppressing variation of contrast of a display image even when dust-proof glass is replaced with crystal materials such as a crystal plate.  <P>SOLUTION: Since the direction of an absorption axis of a polarizing filter 25e on the incident side is in parallel with the direction of an optical axis of a dust-proof plate 74a on the incident side formed of a positive uniaxial crystal material, it is thought that not only a light flux which is made incident in a state of being in parallel with the system optical axis SA but a light flux which is made incident in an inclined state to the system optical axis SA becomes hard to be subjected to a birefringence behavior by the dust-proof plate 74a on the incident side, etc. in passage of the polarizing filter 25e and the dust-proof plate 74a on the incident side. Thus, a phenomenon in which modulated light with a shifted modulation amount is injected by refractive index anisotropy of the dust-proof plate 74a on the incident side is suppressed while raising cooling efficiency by the dust-proof plate 74a on the incident side, is suppressed. Thus, a comparatively satisfactory liquid crystal light bulb 25a with stable viewing angle characteristics regarding contrast ratio is provided.  <P>COPYRIGHT: (C)2010,JPO&INPIT
