Abstract: There is provided a grinding roller for use in a fixing device including a pair of rotary fixing members that rotate while being pressed against each other to form an area of contact, and heat and press a recording medium carrying an unfixed toner image and fed to the area of contact, to thereby fix the unfixed toner image on the recording medium. The grinding roller is configured to grind a surface of a toner image-side rotary member of the pair of rotary fixing members that comes into contact with the unfixed toner image. The grinding roller includes an abrasive grain layer including abrasive grains, forming a surface layer of the grinding roller, and having a surface with irregularities including projections each formed by an aggregate of some of the abrasive grains and larger in size than each of the abrasive grains and recesses formed between the projections.

Abstract: A roller includes a cylindrical body having openings on both ends thereof and a press-fit member fitted in at least one of the openings of the cylindrical body with an outer circumferential face thereof in contact with an inner face of the cylindrical body. The outer circumferential face of the press-fit member is grooved obliquely to an axis of the cylindrical body, and the inner face of the cylindrical body is smooth at least in a portion that contacts the outer circumferential face of the press-fit member.

Abstract: An adhesive sheet (S) is expanded by expanding means (20) with a plate-like article (W) being mounted to a frame (F) after dicing of the plate-like article (W) to increase spacings between individual chips (T), an expanded state of the adhesive sheet (S) is maintained by expansion maintaining means (10), so that the plate-like article (W) is able to be conveyed together with the frame (F) with the spacings between the chips (T) being maintained, thereby preventing adjacent chips (T) from interfering with each other during the conveyance. This allows the plate-like article (W) after the dicing to be conveyed together with the frame (F) without edges of the adjacent chips (T) coming into contact with each other by vibration during the conveyance to cause chipping or microcracks in the edges.
