摘要： In an unattended traveling vehicle which travels along a predetermined traveling path without an operator, an optical device provided at the underside of the vehicle has a light source and a light detector to receive the reflected light from a guide band arranged on a traveling surface of the path. The light detector has a width substantially the same as that of the vehicle, and therefore detects a quantity proportional to shift of the vehicle from the guide band. Thereby, the traveling direction of the vehicle is corrected, and simultaneously various signals can be applied to the vehicle by providing the band with various configurations.

摘要： A toner of a first color incorporated into a development appartaus for second color is charged to a polarity opposite to a polarity of a charge of an electrostatic latent image for the second color by a frictional action with a toner in the development apparatus for the second color. The toner of the first color incorporated into the second development apparatus is caused to adhere to a charge-non-released region of a drum, whereby accumulation of the first toner in the second color development apparatus is prevented. The first and second toners are electrostatically transferred onto a paper by a bias electric field having a polarity opposite to that of the toner images, whereby at reversal development of the second color, the toner of the first color adhering to the charge-non-released region is prevented from being transferred onto the paper. Further, the toner of the first color, incorporated in the second development apparatus, changed reversly in its polarity, or reduced to about zero in the charge quantity can be removed by electrical and mechanical removal means provided in the second development apparatus.

摘要： Non-contact type developing device and method for electrophotographic recording system. The pitch of magnetic poles on a developing sleeve carrying a developer is selected to fall within a predetermined range or is varied such that the pitch increases as the circumferential distance from the point where the gap between the developer carrier member and a photosensitive member is minimum. The bias voltage applied to the developing sleeve is controlled in accordance with a change in the size of the gap between the surface of the photosensitive member and the layer of the developer on the developer carrying member. Alternatively, the bias voltage is applied throughout a period in which the charged region on the photosensitive member is opposed by the developing sleeve.
