    摘要： A toner supply roll including a metal shaft and a cylindrical soft polyurethane sponge structure formed on an outer circumferential surface of the metal shaft by foam molding of a polyurethane material in a mold cavity of a mold. The sponge structure having a hardness of 350 g or lower includes a skin layer having generally smooth surface and openings, and a network of cells. The openings are open in the smooth surface and communicate with respective ones of the cells located adjacent to the skin layer, such that the openings are substantially aligned with central portions of the respective ones of the cells in axial and radial directions of the sponge structure. Each opening has a size within a range of 100-800 .mu.m, and a total area of the openings is at least 20% of a total area of the smooth surface of the skin layer. The method of producing the roll is also disclosed.

    摘要： A toner supply roll including a cylindrical soft polyurethane sponge structure formed on an outer circumferential surface of a metal shaft by foam molding of a polyurethane material in a mold cavity of a mold. The sponge structure having hardness of 350 g or lower includes a skin layer having a network of cells and openings open in its outer circumferential surface and communicating with respective ones of the cells located adjacent to the skin layer, such that the openings are substantially aligned with central portions of the respective ones of the cells in axial and circumferential directions of the sponge structure. Each opening has a size of 100-800 .mu.m, and a total area of the openings is at least 20% of the total surface area of the skin layer. The sponge structure has a plurality of protrusions formed on the outer circumferential surface of the skin layer so as to extend linearly or helically in the axial direction of the sponge structure. The protrusions have a height of 20-3000 .mu.m and are arranged in a circumferential direction of the sponge structure with a pitch of 300-3000 .mu.m, so that the skin layer is provided with recesses each interposed between the adjacent protrusions. Methods of producing the roll are also disclosed.

    摘要： To provide an actuator which is easily made a small size and flexible, and has a large displacement. The actuator comprises a rod-shaped actuator element, having one axial end thereof fixed, including a dielectric film made of a dielectric elastomer and a plurality of electrodes arranged via the dielectric film, in the actuator element, the dielectric film extends as a voltage applied across the electrodes becomes large, and a load member connected to the other axial end of the actuator element and fixed in a state in which the actuator element is permitted to be extended axially, characterized in that making large the voltage applied across the electrodes causes the dielectric film to be extended, whereby the actuator element is extended axially according to the tension of the load member.
