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.

摘要： A flash lamp apparatus for reducing occurrence of spots on a recording paper wherein an overlapping portion formed between two adjacent fusing areas of the recording paper receives a first flash and a second flash from a flash lamp so as to heat and fuse a toner on the recording paper. The overlapping portion is controlled so as to reduce occurrence of spots on the recording paper by reducing an area of the overlapping portion on a recording paper. Such reduction in the overlapping portion may be obtained by controlling a frequency of the flash or controlling a feeding velocity of the recording paper. Alternatively, the fusing energy of the overlapping portion may be reduced by changing alternately the radiating energy.

摘要： Disclosed is an electrical power supply for use, for example, for a flash fusing device in an electrophotographic recording apparatus, in which a DC high voltage is generated from a low voltage of an AC power supply so that the high voltage DC energy is momentarily consumed or discharged. The electrical power supply is configured in a manner so that, in order to make unnecessary a charging capacitor and a current limiting resistor for preventing rectifier elements from being damaged, at least some of the rectifier elements are constituted by rectifying control elements such as thyristors or transistors and a control signal is given to those rectifying control elements so as to make the rectifying control elements be in an isolated state. By use of such a configuration, the electrical power supply can be reduced in size as well as in power loss. The effect can be fully exhibited not only in a fusing apparatus employing the electrical power supply but in a recording apparatus employing such a fusing apparatus.

摘要： An aerial recording sheet carrier is provided downstream of a fixing station. The aerial recording sheet carrier has one pair of pressure chambers with wall surfaces facing each other and in parallel. Air jets are arranged on opposite wall surfaces of the pressure chambers. A recording sheet and a toner image from the fixing station are carried by an air stream and cooled down. The toner image on the recording sheet, which is in fusion, is prevented from coming into contact with any parts, such as a recording sheet carrying passage. Thus a stain on parts due to contact with the toner image can be prevented.

摘要： A developing device is of non-contact development type in which a toner is jumped to a photoconductor to develop a latent image on the photoconductor. The developing device is controlled in height of a developer-agent layer on a developer roll, and sets a developing gap between the photoconductor and the developer roll in such a manner that a driving electric field required for jumping of the toner can be maintained at the air gap between the photoconductor and a developer-agent layer on the developer roll and developing bias voltage can be brought to a value lower than charged electric potential of the photo-conductor. By setting the developing bias voltage to the valve lower than the charged electric potential of the photoconductor, jumping of additional or unnecessary toner is restricted so that contamination of an image and a recording sheet can be prevented. Further, a multi-color recording apparatus having this developing device prevents toner developer agents different in color from being brought into contact with each other to form a clear multi-color image without mixing in color and contamination.
