  • Publication number: 20200208579
    Abstract: An intake-air temperature controlling device for an engine is provided, which includes an engine body, an intake passage, an air intake part, an intake air temperature adjuster configured to adjust air temperature taken in through the air intake part to the passage, and a controller. An operating range in which the CI combustion is performed has a lean operating range in which A/F of mixture gas formed inside the cylinder, or G/F that is a relationship between the total weight G of gas inside the cylinder and a weight F of fuel fed to the cylinder is relatively low, and a rich operating range in which the A/F or G/F is relatively high. When the engine is in the lean operating range, the controller outputs a control signal to the intake air temperature adjuster so that the air temperature is increased, as compared in the rich operating range.

  • Patent number: 8086151
    Abstract: A mono-component developing apparatus including a developing roller which transports toner supported on an outer circumferential face of a center portion toward a developing area by rotating while frictionally sliding on a sealing member on each of two end portions. The developing roller includes surface processing areas having a spiral shape, placed on each of outer circumferential faces of the two end portions. An angle, made by a spiral direction of each surface processing area and the rotation direction, is an acute angle. The developing roller inhibits toner leakage, with the driving torque of the developing roller being only slightly increased.

  • Patent number: 7853161
    Abstract: A potential difference between the photoreceptor and the development roller is set at a value at which the normally charged toner on the development roller can be flown toward the photoreceptor in the development phase at the time of compulsorily consuming the toner, and this potential difference is set at a value at which the flown normally charged toner can be returned to the development roller in the recovery phase.

  • Publication number: 20100209123
    Abstract: A toner cartridge for a printer includes a species detection key which forms a part of an outer shape of the cartridge and an IC chip which stores individual information, wherein a part of a harness for connecting to the IC chip or between the IC chip and a connector portion is mounted on the species detection key. A main body of the printer has a key receiving portion which mates with the species detection key. Thereby, the printer can detect erroneous attachment of a cartridge at early stage and surely cope with various types of cartridges requiring only compact space with the aid of its detection means.

  • Patent number: 7742709
    Abstract: An image forming apparatus comprises a cartridge equipped with a toner reservoir, and an apparatus body. The cartridge is attached to the apparatus body when used and developer in the toner reservoir is used for image development. The cartridge comprises a storage unit which is provided inside the toner reservoir and capable of communicating with the apparatus body. The apparatus body comprises a communication unit which is capable of communicating with the storage unit and communication state between the storage unit and the communication unit varies depending on amount of residual developer in the toner reservoir. Thus there is provided a developer cartridge and an image forming apparatus surely capable of carrying out both residual-toner-amount detection and transmission of cartridge information with space saving design.

  • Publication number: 20090175636
    Abstract: To prevent image defects such as fog and irregularities caused by the accumulation of the oppositely charged toner by flying the toner toward a photoreceptor to compulsorily consume the toner even though the toner is oppositely charged toner having a small charged amount. A potential difference between the photoreceptor and the development roller is set at a value at which the normally charged toner on the development roller can be flown toward the photoreceptor in the development phase at the time of compulsorily consuming the toner, and this potential difference is set at a value at which the flown normally charged toner can be returned to the development roller in the recovery phase.

  • Patent number: 6070039
    Abstract: An apparatus for removing developer from a developer carrier includes a developer-charge-eliminating means including a first elastic member. The first elastic member is electrically conductive and contacts the developer carrier with an uneven surface. Preferably, the uneven surface includes exposed cells of a foamed body. The uneven surface of the first elastic member insures that sufficient contact and frictional resistance is applied to excess developer on a developer carrier. Preferably, the first elastic body is backed by a backing member which is more flexible than the first elastic member. The flexible second elastic body further insures that the charge-eliminating member sufficiently contacts the developer carried by the developer carrier even with extended use.
