摘要： A semiconductive roller is provided which includes a roller body formed from a highly extrudable rubber composition containing an SBR and an epichlorohydrin rubber in combination as a rubber component, the roller body having a higher production yield and higher toner imaging durability, and unlikely to suffer from reduction in image density due to adhesion of toner and a contact mark on an outer peripheral surface thereof with a smaller compression set. In the rubber component, the SBR and the epichlorohydrin rubber are present in an SBR excess state. In the rubber composition, a crosslinking component for crosslinking the rubber component includes a sulfur crosslinking agent and 0.75 to 3 parts by mass of a thiazole accelerating agent based on 100 parts by mass of the rubber component. The roller body (2) of the semiconductive roller (1) is made of a crosslinking product of the rubber composition.

摘要： An electrically conductive rubber composition is provided, which comprises a rubber component including an SBR, an EPDM and an epichlorohydrin rubber, a crosslinking component and an azodicarbonamide foaming agent having an average particle diameter of 3 to 11 μm. The azodicarbonamide foaming agent is blended in a proportion of 0.5 to 8 parts by mass based on 100 parts by mass of the overall rubber component. A transfer roller (1) is produced by extruding the electrically conductive rubber composition into an elongated tubular body, and continuously feeding out the tubular body in the elongated state without cutting the tubular body to continuously pass the tubular body through a microwave crosslinking device and a hot air crosslinking device to continuously foam and crosslink the tubular body.

摘要： An electrically conductive rubber composition is provided, which is usable for production of a transfer roller of a highly flexible foam satisfying requirements for cost reduction and weight reduction and having smaller foam cell diameters and, hence, ensuring higher-quality image formation with smaller environment-dependent variations in roller resistance. A transfer roller produced from the electrically conductive rubber composition, a production method for the transfer roller, and an image forming apparatus including the transfer roller are also provided. The electrically conductive rubber composition contains a rubber component including SBR and/or BR, EPDM and epichlorohydrin rubber, a crosslinking component, and 4 to 6 parts by mass of a foaming agent and 1.5 to 2.7 parts by mass of a foaming assisting agent based on 100 parts by mass of the rubber component. The transfer roller (1) is produced by extruding the electrically conductive rubber composition into a tubular body and performing an in-can vulcanization process on the tubular body. The image forming apparatus incorporates the transfer roller.
