摘要： An image processing apparatus eliminates a detection error in a color offset detecting operation due to a periodic fluctuation in a speed of a conveying belt which conveys a transfer sheet on which color component images are transferred and superimpose to form a multi-color image. A plurality of image forming units are arranged along the conveying belt, each of the image forming units transferring a color component image on the transfer sheet and also transferring a register mark on the conveying belt. A register mark detecting sensor located along the conveying belt detects the register mark on the conveying belt. A distance between the register mark detecting sensor and one of the plurality of image forming units adjacent to the register mark detecting sensor is a multiple of an integer of a circumference of the drive roller. A distance between adjacent ones of the plurality of image forming units is a multiple of an integer of the circumference of the drive roller.

摘要： A holder device for handling a replaceable image carrier of an image forming apparatus. A photoconductive element mounted in an electrophotographic copier or similar apparatus and to which toner adheres can be dismounted and replaced with a new photoconductive element with ease and without touching it. A box-like holder has receiving sections for accommodating the old and new photoconductive elements individually. The receiving sections are each provided with guide slots for grasping and guiding opposite ends of a shaft on which a photoconductive element is mounted and openings each being contiguous with a respective one of the guide slots, said guide slots and openings being formed through each of opposite end walls of a housing of the holder device. Lugs are provided on the end walls of the housing to cancel the restraint of restraining members which prevent the ends of a shaft of a photoconductive element from slipping out of the copier, as the holder is sequentially moved into the copier.

摘要： A monolithic photosensor array comprises first, second and third identical photodiodes. A light emitting diode illuminates the third photodiode continuously. An occluder disc is rotatably driven from the shaft of a servo motor between the light emitting diode and the first and second photodiodes. The disc is formed with a plurality of circumferentially spaced apertures which alternately cover and uncover the photodiodes which produce quasisinosoidal position signals in response thereto, the position signals of the first and second photodiodes being relatively 90.degree. out of phase. A computing circuit produces a motor shaft velocity command signal corresponding to the number of steps the shaft must rotate from the initial position to the new desired position and progressively reduces the magnitude of the velocity signal in response to the position signals. A differentiating circuit differentiates the position signals and their inversions and a commutator produces an actual velocity signal by sampling the peak values of the differentiated position signals. A comparator compares the velocity signal with the velocity command signal and produces an error signal corresponding to the difference therebetween which is fed to the motor as a drive signal. A sensor senses the output voltage of the third photodiode and an intensity control circuit adjusts the current flow through the light emitting diode until said output voltage has a predetermined value, thereby compensating for ambient temperature and other variations of all three photodiodes. A stable reference voltage for the apparatus is derived from the sensor.

摘要： A developing device that efficiently adjusts the amount of charge on the developing agent without being affected by external conditions, and that continuously supplies a developing agent with the appropriate toner concentration and amount of charge. An ionized air flow adjusts the amount of charge on the developing agent discharged from the developing unit to improve the dispersability of the replenished toner without applying unnecessary stress. The developing agent is raised upwards by a screw, downwards by an agitation member, and then gathered by a screw in a circulating flow. Consequently, the developing agent is uniformly mixed within the developing agent agitation unit. This circulating flow of the developing agent increases the probability of contact and reduces damage to the developing agent. When the ionized air flow reduces the amount of charge before agitation, the toner can be uniformly charged to the appropriate value.
摘要翻译：一种显影装置，其不会受到外部条件的影响而有效地调节显影剂上的电荷量，并连续地向显影剂提供适当的调色剂浓度和电荷量。离子化空气流量调节从显影单元排出的显影剂上的电荷量，以改善补充调色剂的分散性，而不施加不必要的应力。显影剂由螺杆向上升起，由搅拌构件向下升起，然后通过螺杆在循环流中聚集。因此，显影剂在显影剂搅拌单元内均匀混合。显影剂的这种循环流动增加接触的可能性并减少对显影剂的损害。当电离空气流减少搅拌前的电荷量时，调色剂可以均匀地充电到适当的值。
