  • Patent number: 9637623
    Abstract: A rubber composition contains a higher ethylene content EPDM and a lower ethylene content EPDM as a rubber component. The proportion of the higher ethylene content EPDM is 30 to 80 mass % based on the overall amount of the rubber component. The rubber composition is less susceptible to reduction in friction coefficient ? and has a proper hardness, a smaller permanent elongation and an excellent abrasion resistance after crosslinking. Therefore, the rubber composition is suitable for a sheet conveying roller and an image forming apparatus incorporating the sheet conveying roller.

  • Patent number: 8401430
    Abstract: An electron emitting element (1) includes a substrate (2), an upper electrode (3), and a fine particle layer (4) sandwiched between the substrate (2) and the upper electrode (3). The fine particle layer (4) includes metal fine particles (6) with high resistance to oxidation, and insulating fine particles (5) larger in size than the metal fine particles (6). The electron emitting element (1) can steadily emit electrons not only in vacuum but also in the atmosphere. Further, the electron emitting element (1) can work without electric discharge so that harmful substances such as ozone, NOx, or the like are scarcely generated. Accordingly, degradation of the electron emitting element (1) due to oxidation does not occur. Therefore, the electron emitting element (1) has a long life and can steadily work continuously for a long period of time even in the atmosphere.
