摘要： 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.

摘要： 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. A development duty and a frequency f are set in such a way that a time period in the development phase is larger than a time taken for the normally charged toner on the development roller to fly to a point located midway between the development roller and the photoreceptor and is smaller than a time taken for arriving at the photoreceptor, and a time period in the recovery phase is larger than a time taken before the normally charged toner arrived at the point located midway between the development roller and the photoreceptor arrives at the photoreceptor, returns to the development roller to beaten out the oppositely charged toner and the oppositely charged toner beaten out flies to the photoreceptor.
摘要翻译：为了防止由于相反充电的调色剂的积聚引起的图像缺陷，例如通过将调色剂朝向感光体飞行而强制消耗调色剂，即使调色剂具有相反电荷的带电量小的调色剂。感光体和显影辊之间的电位差被设定为在强制消耗调色剂时显影辊上的正常带电的调色剂能够在显影阶段中朝向感光体流动的值，并且设定该电位差在正常充电的调色剂可以在恢复阶段返回到显影辊的值。显影负荷和频率f被设定为使得显影阶段的时间段大于显影辊上的正常充电的调色剂飞行到位于显影辊和感光体之间的位置的时间并且小于到达感光体所需的时间，并且恢复阶段的时间段大于在正常充电的调色剂到达位于显影辊和感光体之间的位置到达感光体的时间，返回到显影辊，以殴打带相反电荷的调色剂，并将带相反电荷的调色剂扑灭到感光体中。

摘要： 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.

摘要： 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.
