A support for rotationally movable mounting of solar modules configures an outer shaft as a tube and mounts an inner shaft in it, by way of a calotte element in the end position, so that this element is accommodated in the outer shaft in longitudinally displaceable and tiltable manner, as well as in freely rotational manner, if necessary. In this way, only one roller block is required, even if two uncoupled connection shafts are to be mounted.

The present disclosure provides a charging member for electrophotographic equipment capable of providing constant and excellent uniform chargeability over a long period of time from low-temperature and low-humidity through high-temperature and high-humidity environments, while suppressing bleeding. A charging member for electrophotographic equipment includes an elastic layer and a surface layer formed around the elastic layer. The elastic layer includes the following (a) through (c): (a) an ion conducting agent that is solid at room temperature; (b) an ion conducting agent that is liquid at room temperature; and (c) an electron conducting agent with an average grain diameter of 25 to 90 nm and a DBP absorption of 152 ml/100 g or below.

A conductive roller for electrophotographic device is provided, in which the agglomeration of carbon black to be blended is suppressed and the surface layer of the conductive roller has excellent resistance uniformity when a water-based coating is used. The conductive roller for electrophotographic device 10 including a shaft body 12, an elastic body layer 14 formed on the outer periphery of the shaft body 12, and a surface layer 16 formed on the outer periphery of the elastic body layer 14, and the surface layer 16 is formed from an emulsion composition containing the following (a) to (d): (a) an aqueous polyurethane resin, (b) a urethane curing agent, (c) an associative thickener, and (d) carbon black.

A conductive roll for electrophotographic device is provided. The conductive roll for electrophotographic device 10 includes a shaft body 12 and a non-foamed elastic body layer 14 formed on an outer periphery of the shaft body 12. The elastic body layer 14 is made of a cross-linked product of a silicone rubber composition containing the following (a) to (d), and a secondary particle diameter of the following (d) in the elastic body layer 14 is within a range of 100 to 500 nm. (a) is an organopolysiloxane, (b) is a crosslinking agent, (c) is a microcapsule catalyst made of fine resin particles which encapsulate a crosslinking catalyst by a resin other than a silicone resin, and (d) is silica with a BET specific surface area of 70 to 350 m.sup.2/g.

A handle supporting a mat roller head at an angle to the handle to make applying force to the adhesive acoustic damping mat easier in tight spaces. The angle is optionally adjustable. The roller head includes arms supporting a roller with a two-dimensionally corrugated surface to enable applying adhesive acoustic damping mats to irregular surfaces. Additionally, the roller head supports two LEDs to improve visibility of the workspace when adhesive acoustic damping mats are being applied. Power for the LEDs comes from batteries in a battery compartment in the handle. The screw-on battery compartment cap includes an ON/OFF switch. The handle has a top thumb rest and a bottom finger rest and has a partial tactile engagement surface.
