  • Patent number: 11402921
    Abstract: A spatial sensing region is set in accordance with a spatial sensing function of a first operation detection unit included in a first operation device, and another spatial sensing region is set in accordance with a spatial sensing function of a second operation detection unit included in a second operation device. The first operation device and the second operation device are arranged in a vehicle interior. For example, when the second operation detection unit of the second operation device detects a forward movement of a hand, it is determined that an operator intends to operate the first operation device and control is performed such that a display screen of the first operation device is turned on, for example.

  • Patent number: 9223254
    Abstract: An image forming apparatus is configured to form a toner image by a toner image forming portion on an intermediate transfer belt, to transfer the toner image to a transfer and fixing belt, and to form a toner film by heating and pressurizing the toner image on the transfer and fixing belt. The transfer and fixing belt includes an elastic layer and when the toner film is pressurized to a recording medium in a body at a toner film transfer portion, the toner film is pressed to the recording medium while following surficial ruggedness of the recording medium. Because the toner image is formed by using toner particles containing a thermoplastic elastomer having crystallinity, the toner film formed of this toner image is fully resilient.

  • Patent number: 9037061
    Abstract: A fixing apparatus includes a back-up member contacting an inner surface of a cylindrical belt; a roller having an elastic layer and contacting an outer surface of the belt, the roller being cooperative with the back-up member to form a fixing nip between the belt and the roller. A sheet carrying a toner image is nipped and fed through the fixing nip, during which the unfixed toner image is heat-fixed thereon by the fixing nip. The back-up member includes a portion contactable with the inner surface and having such a configuration that the belt forms a first curved surface convex toward the roller in an upstream region in the fixing nip with respect to a moving direction of the belt and that the belt forms a second curved surface convex toward the back-up member in a downstream region in the fixing nip with respect to the moving direction.
