    摘要: A novel epoxy resin composition is prepared by first mixing 100 parts by weight of an epoxy resin having an epoxy equivalent of no more than 200 with 0.5-10 parts by weight of a phenoxy resin to form a uniform mixture, then blending the mixture with a curing agent (i.e., a condensation product of a polybasic carboxylic acid and bisphenol A) and an inorganic filler. The epoxy resin composition has a suitable degree of rigidity and softness within the molecular chain without sacrificing its resistance to heat or thermal shock and will not cause precipitation of any portion of the filler in the resin composition. This resin composition is useful in the making of cast insulators employed in electric machines.

    摘要: A cleaning device for use in an image forming apparatus which includes an image carrier, an image forming device to form a toner image on the image carrier, and a transferor to transfer the toner image from the image carrier onto a recording sheet, in which the cleaning device cleans a residual toner on the image carrier after transferring. The cleaning device includes a cleaning blade to scrape off the residual toner on a circumferential surface of the image carrier, a contacting member to bring a tip end of the cleaning blade into contact with the circumferential surface of the image carrier in a direction upstream of a moving direction of the image carrier when a cleaning operation of the blade is conducted, and a releasing member to release the tip end of the cleaning blade from the circumferential surface. The blade is made of an elastic member having a coefficient of dynamic friction between the blade and the image carrier of 0.15 to 0.4.
