摘要： In a multi-stage roll magnetic brush type of developing device, at least two opposite direction rotation rolls which rotate in an opposite rotation direction to that of a photosensitive body are arranged adjacently and oppositely to a photosensitive body, and at least one same direction rotation developing roll which rotates in the same rotation direction as that of the photosensitive body is arranged adjacently, oppositely to the photosensitive body and upstream of the opposite direction rotation developing rolls in the rotation direction of the photosensitive body. Thus, the path of carrying the developer by the same direction rotation developing roll and the opposite direction rotation developing rolls can be optimized. In the wide area printing at high speed, an image with stabilized printing quality can be obtained without an increase in the production cost.

摘要： A gear includes a gear body which includes a rim integral with a plurality of teeth at an outer peripheral surface thereof, and a boss disposed concentrically inside the rim. The gear further includes at least fitting section which is formed from a material having a low hardness and a low flexural strength as compared with a material for forming the gear body, and which is provided between the rim and the boss, so that the gear with a rotational-power transmitting member fitted into the fitting portion is rotated, whereby the rotational power of the gear body is transmitted to the rotational-power transmitting member, while elastically deforming the fitting section to absorb a predetermined amount of a shock produced with the rotation of the gear body. In such gear, the gear body and the fitting section are formed integrally with each other by a two-color molding process. Thus, it is unnecessary to produce a buffering member made of a rubber separately from the gear body and to amount the buffering member to the gear body. Therefore, it is possible to decrease the number of parts and the number of producing steps to reduce the producing cost. In addition, the fitting section cannot be separated from the gear body, leading to an enhanced quality of a gear product.

摘要： A toner supply control system of the electrophotographic apparatus which includes a developing unit 3 for developing with a developer composed of toner and carrier; a toner hopper 4 for storing the toner; a toner empty sensor 7 for detecting the remainder of toner in the toner hopper 4; and a toner supply drive unit 5 for conveying toner from the outside of the apparatus into the toner hopper 4. Toner is conveyed from the outside into the toner hopper 4 by driving the toner supply drive unit 5 over a predetermined period of time without stopping the operation of the electrophotographic apparatus when the toner empty sensor 7 detects over a predetermined period of time that the remainder of toner in the toner hopper 4 is small. Then the existence of an output signal outputted from the toner empty sensor 7 indicating that the remainder of toner is small is detected, and a previous signal of toner shortage is output while the developing operation of the electrophotographic apparatus is being maintained in the case of existence of the output signal, and the shortage of toner is reported to an operator in accordance with the previous signal of toner shortage.
