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： 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： In a heat roll consisting of a mandrel and a surface layer, this invention comprises a fixing apparatus and a recording apparatus, wherein a thickness of the surface layer is formed not exceeding the thickness determined by a square root of the product of a heat diffusion rate of the surface material and a nip time required for a form to pass a nip zone, and a thickness of the mandrel is formed not less than the thickness determined by a square root of the product of a heat diffusion rate of the mandrel material and a one rotational period of the mandrel. Since the surface layer and the mandrel are so specified for the thickness as mentioned, a quantity of heat flowing from the mandrel into the surface layer multiplies, and thus a high fixing strength is obtainable. The fixing apparatus and the recording apparatus are provided further with a cleaning device high in cleaning capacity.

摘要： An ink jet printer is of a small size and is capable of printing high-quality images, wherein an ink with a colorant dispersed in a solvent is ejected in a direction lower than a horizontal level and is adhered to a surface of a recording medium. The recording medium is conveyed while being spaced a constant distance from ink ejecting electrodes, thereby stabilizing an electric field induced between the ink ejecting electrodes and the recording medium and stabilizing the amount of the ink ejected.

摘要： An ink jet recording apparatus has a head substrate, a jetting member disposed on the substrate, a recording electrode disposed so as to sandwich the jetting member and for making ink jet from the jetting member, and a separating wall for covering the recording electrode, wherein the ink is supplied from the proximal end of the jetting member and recovered in an upward direction from near the tip end of the jetting member. According to such an arrangement, it becomes possible to prevent the recording electrode from being clogged with ink adhering at the tip end thereof, and thus, the locus of the ink drop jetted from the head can be prevented from being deviated due to deviation of the jetting point on the jetting member. Accordingly, it becomes possible to provide an ink jet recording apparatus which is capable of printing an image with a high definition.
