Upon being subjected to a slide-contact with another member, the material exhibits a high degree of abrasion resistance and at the same time is capable of effectively protecting the material of a member operatively cooperating therewith in slide-contact. The material is thus highly suitable for very frequent slide-contact with a cam member or the like.

As a modified embodiment of the present invention, an alloy containing Fe--Mo as a main component may be dispersed into the iron-based matrix in place of the aforesaid Fe--P--C ternary alloy phase. Said Fe--P--C ternary alloy phase may be prepared by mixing a single metal element, Fe, C and P into the powdered raw material of the iron-based matrix. Alternatively, said Fe--P--C ternary alloy phase may be prepared by mixing Fe--P--C alloy powder into the powdered raw material of the iron-based matrix. Further, an alloy containing Fe--Mo as a main component may be prepared by mixing Fe--Mo--Si alloy powder into the powdered raw material of the iron-based matrix.

    摘要: An image forming apparatus includes a developing device. The developing device includes a toner carrier (developing roller). The developing roller includes a base member, electrode bars, a pair of electrodes, and a protection layer. The base member includes a conductive core and an insulating layer formed on the outer surface of the core. The electrode bars and the pair of electrodes are made of a conductive metal, and are provided on the outer surface of the insulating layer. The electrode bars and the pair of electrodes are formed in a way that an unnecessary portion of a metal film is irradiated with a laser beam and thus is removed. The electrodes are each formed helically on the outer surface of the base member 1 and formed to taper down toward the outmost side thereof in its cross section.

    摘要: Disclosed is a technology that specifies each of a plurality of two-dimensional codes in an image and reduces the processing time for judging color in each cell region in each specified two-dimensional code. Based on edge images generated from obtained images, candidate regions among these edge images are extracted, a judgment is made about whether or not a characteristic pattern is included in each of the corresponding regions in the original images that correspond to these extracted candidate regions, and then the two-dimensional code regions are detected from among the original images. The color is judged both for each pixel group that comprises each row of that region and for each pixel cell, in pixel array order. If it is determined that a certain number or more pixels in each row that corresponds to each cell region are included in the color judgment region, color judgment is omitted for the remaining pixels in that row.
