Abstract: A multifunction device includes a scanner for scanning an image from an original document, and a printer body provided with an image-forming unit for forming an image on a paper based on image data read by the scanner. The scanner is provided on the front side of the main printer body, and a control panel is integrally provided with a scanner cover, which covers the scanner. This construction enables production of a compact device having a small footprint and enables the user to supply paper to the scanner, remove the discharged original document, and operate the control panel in the same vicinity, thereby improving operability.

Abstract: A developing cartridge has a housing that accommodates developer therein. Rotatably mounted in the housing is a developing roller. The housing has side seals provided at each end of the developing roller that oppose the circumferential ends of the developing roller. The developing roller itself is divided into a seal region, a side-end region and a center region. A portion of the seal region and the side-end region found at each end of the developing roller with the seal region portions being at the ends of the roller and the side end region portions being between the seal region portions and the center region. Opposing the developing roller is a toner thickness regulating blade having a presser portion. The presser portion has a discontinuous cross-section such that a greater portion of the presser member contacts the developer roller in each portion of the side-end region then contacts the developer roller in the center region. As a result, a greater pressure is applied between the presser portion and the developer roller at the side-end region thereby resulting in less toner being applied to the developing roller to be carried to a photosensitive member. To further the minimize the amount of toner applied to the developing roller, the roughness in the side end region of the developing roller is smaller than the roughness in the center region and the hardness in the side end region of the developing roller is greater than the hardness in the center region. This combination of factors prevents toner from leaking from the housing at the ends of the developing rollers.

Abstract translation: 显影盒具有容纳显影剂的壳体。 可旋转地安装在壳体中的是显影辊。 壳体具有设置在显影辊的与显影辊的周向端相对的每一端处的侧密封件。 显影辊本身被分为密封区域，侧端区域和中心区域。 在显影辊的两端处的密封区域和侧端区域的一部分，密封区域位于辊的端部，侧端区域位于密封区域部分和中心区域之间。 与显影辊相对的是具有压脚部分的调色剂厚度调节片。 按压部分具有不连续的横截面，使得较大部分的压紧构件在侧端区域的每个部分中与显影辊接触然后在中心区域中与显影辊接触。 结果，在侧端区域的压紧部分和显影辊之间施加更大的压力，从而导致较少的调色剂被施加到显影辊上以被运送到感光部件。 为了进一步减少施加到显影辊的调色剂的量，显影辊的侧端区域中的粗糙度小于中心区域的粗糙度，并且显影辊的侧端区域中的硬度大于 硬度在中心区域。 这种因素的组合防止调色剂在显影辊的端部处从壳体泄漏。

Abstract: Even with an extend use of a laser printer, toner leakage can be prevented. A side seal disposed at each end of a developing roller includes a sealing member that makes sliding contact with a surface of the developing roller and a sponge seal that supports the sealing member. The sponge seal includes a base portion and a projecting portion. The base portion has a substantially rectangular shape, to which the sealing member is affixed. The projecting portion projects from the center of the base portion toward the inside of the developing roller along its length, without being caught between a supply roller and the developing roller.

Abstract: In a color laser printer, each scanner unit as an exposure scanning unit is positioned on a lateral side of a developing unit, so as not to face the surface of a photoconductor drum as a photoconductor. The scanner unit emits a laser light scanned in a direction perpendicular to a rotation axis of the photoconductor drum. A last mirror, having a reflecting surface at an angle of 45° with respect to the direction of the rotation axis of the photoconductor drum, is arranged to face the surface of the photoconductor drum. The last mirror reflects the laser light emitted by the scanner unit in the direction of the rotation axis of the photoconductor drum and changes the traveling direction by 90° to irradiate the surface of the photoconductor drum. This configuration allows a process cartridge including the developing unit to be attached and detached from above.

Abstract: In order to prevent toner leaks from both sides of a developing roller disposed within a case accommodating polymerized toner, side seals each having a TEFLON® (polytetrafluoroethylene) felt member on its surface are provided to make sliding contact with a surface of the developing roller. In addition, “Hanarl FL-Z75” (80-90 wt. % hydrofluorocarbon and 10-20 wt. % polytetrafluoroethylene) manufactured by Kanto Kasei Ltd., is used as a lubricating agent for the TEFLON® felt members to make them more lubricative. Accordingly, noise generated by the side seals sliding contact with the developing roller can be reduced. To prevent toner leaks from the sides of the developing roller, a film or resin stopper is disposed at a lower-end front edge of the case to stop the toner.
