    摘要： A fixing device (40) includes a fixing belt (43) rotatable in a rotation direction and a nip former (41) stretching the fixing belt (43). A pressure rotator (45) presses against the nip former (41) via the fixing belt (43) to form a fixing nip (N1) between the fixing belt (43) and the pressure rotator (45), through which a recording medium is conveyed. A separator (48) is disposed downstream from the nip former (41) in a recording medium conveyance direction and stretches the fixing belt (43). A presser (49) is interposed between the fixing nip (N1) and an upstream end (48a) of the separator (48) in the rotation direction of the fixing belt (43). The presser (49) comes into contact with an inner circumferential surface of the fixing belt (43) to press the fixing belt (43) against the pressure rotator (45).

    摘要： An apparatus (76) for forming a shadow mask from a mask blank (70) includes a punch (78) having a convex surface (80), a pad (82) having a complementary concave surface (84), and upper and lower dies (86,88) having openings (90,92) therein for receiving the punch and the pad, respectively. Each die also has a complementary nonplanar surface (96,94) with inner edges (106-112,98-104) adjacent the opening for clamping the mask blank. Each die surface has a surface contour that substantially matches the extended surface contour of the mask blank when the mask blank lies against the inner edges (98-104) of the lower die surface (94), so that wrinkling does not occur when the mask blank is clamped between the upper and lower dies.

    摘要： A fixing device includes a fixing roller, a pressure roller, and a regulation member. The fixing roller includes a roller member and a fixing belt. The roller member includes a shaft which extends in one direction and an elastic layer integrally formed on the shaft. Each regulation member has an annular regulation surface which opposes a side edge of the fixing belt, and is configured to regulate movement of the fixing belt in a rotation axis direction. The regulation surface is inclined relative to a line perpendicular to the rotation axis as viewed on a cross-section parallel to the rotation axis. The regulation surface is inclined from the rotation axis side such that the closer the regulation surface is to an outside, in a radial direction, of the fixing roller, the closer the regulation surface is to a center, in a length direction, of the shaft.

    摘要： A belt unit includes an endless belt member, a first roller provided on an inner circumferential surface side of the belt member, and a stretching member provided on the inner circumferential surface side of the belt member. The stretching member is configured to stretch the belt member. A circumferential length of the belt member at a center portion in a widthwise direction of the belt member is shorter than a circumferential length of the belt member at an end portion in the widthwise direction of the belt member.

    摘要： An electromagnetic induction exothermic roller (21) having, in the order from the surface, at least a release layer, induction exothermic layer (22), an elastic layer (23), and a core (24). Exothermic roller (21) is pressed by a press member (31) to form a nip portion (34) and heat up a heating subject material (11) passing through the nip portion (34). The induction exothermic layer (22) has a layer prepared by dispersing an electrically conductive filler in the base material consisting of a heat resistant resin or heat resistant rubber. For this reason, the induction exothermic layer (22) can easily deform, so that a nip portion (34) having a large width (W) can be formed. Further, the durability of the induction exothermic layer (22) against repeated bending is improved
