Abstract: A developing roller (1) includes a highly conductive shaft (2) and a conductive elastic layer (3). When the developing roller carring a one-component developer thereon comes in contact with or in proximity to an image forming body, the developer is supplied from the roller to a surface of the image forming body, thereby forming a visible image on the image forming body surface. The elastic layer (3) has applied to its surface a resin component having an elongation at rupture of less than 10% as measured according to JIS K7113. The developing roller ensures that images of high quality are reproduced without a drop of image density over a long period of time.

Abstract: A developing roller comprising a conductive layer formed around a shaft carries a non-magnetic one-component developer on its outer surface to form a thin film of the developer and contacts a photoconductor drum having an electrostatic latent image borne on its surface whereby the latent image is developed to form a toner image. In one embodiment, the surface of the conductive layer has a DIN 4776 core roughness depth Rk of 0.5-3.5 .mu.m in a circumferential direction of the roller, and the ratio of circumferential Rk to axial Rk is greater than 1.0. In another embodiment, the surface of the conductive layer is provided with microscopic ridges and recesses which are alternately disposed in a rotational direction to define wavy streaks having a longitudinal direction substantially aligned with an axial direction of the roller.

Abstract: A developing roller is adapted to carry a developer on its surface and come in contact with or close to a photoconductor drum having an electrostatic latent image borne on its surface whereby the developer is supplied to the drum to visualize the latent image. The developing roller includes a highly conductive shaft and an elastic layer with conductivity formed around the shaft. The elastic layer is surface treated so as to have a resin component which contains a urea resin and/or melamine resin. The roller satisfies log(R.sub.2 /R.sub.1).ltoreq.4.5 wherein the untreated roller has a resistance R.sub.1 and the roller with the resin component has a resistance R.sub.2. The developing roller does not contaminate the photoconductor drum and ensures that images of quality are reproduced without a density variation and background fog over a long time.

Abstract: A developing roller (1) having a thin layer of a developer (4) carried thereon and a drum (3) bearing an electrostatic latent image on its surface are rotated in close relationship, thereby feeding the developer (4) to the surface of the drum (3) for visualizing the electrostatic latent image thereon. The ionization potential of the developing roller (1) surface is adjusted to be below the ionization potential of the developer (4) surface when the developer is charged negative and above the ionization potential of the developer (4) surface when the developer is charged positive. The developer has an ionization potential of 4.5-5.5 eV. When using negatively charged developer, the development roller should preferably contain a lubricant or non-ionic surfactant and should preferably be made of a polyurethane containing a polyisocyanate so as to obtain the desired ionization potential.

Abstract: A developing roller supports a one-component developer on a surface thereof in the form of a thin layer, and is brought in contact with or in proximity to an image forming body in such a state, to supply the developer on a surface of the image forming body, thereby allowing a visible image to be formed on the surface of the image forming body. The developing roller includes: an elastic layer having an ionically conductivity whose surface is imparted with a resin component having a high resistivity. Thus, if R1 is a resistance of the roller in a stationary state and R2 is a resistance of the roller in a rotational state, a relationship of R1>R2 is established. With this developing roller, it is possible to obtain a high quality image and a high gradient.

Abstract: A heat-transfer material includes a tubular body made of a metal. The body includes on an inner surface thereof a porous electroplated layer having re-entrant cavities. A heat transfer material is produced by: preparing a body of a metal serving as a cathode and forming a hydrophobic film on a surface of the body; subsequently keeping the surface of the body and an anode in contact with a plating aqueous solution; and subsequently applying a direct electrical potential betwee the anode and the cathode to cause plating current to flow through the plating solution to lay deposits of plating metal on the surface of the body and laying a number of particulate bubbles on the hydrophobic film on the surface of the body so that the bubbles are enveloped by the metal deposits to form on the surface of the body a porous plated layer having re-entrant cavities.
