    摘要: An ink transfer printer has an electrically-insulated base plate. An array of electric heater elements, aligned with each other, is provided on a surface of the base plate, the heater elements being selectively and electrically energized in accordance with a series of digital image-pixel signals. A frame member, having an opening, is securely provided on the base plate such that the array of elements is encompassed by the opening of the frame member. A sheet of film covers the frame member such that the opening of the frame member is defined as an ink space fillable with ink, and the film sheet has a plurality of fine pores arranged along the array, with at least one of the plurality of fine pores being allocated to each of the heater elements. A heat dissipating conductor is formed of a thermal conductive material, and is associated with the film sheet such that thermal energy, locally generated by an electrical energization of at least one of the electric heater elements, is promptly dissipated.

    摘要: A plurality of thermal heads for different colors, are disposed in parallel in a line-printing direction, being offset with respect to each other in a transport direction along which an image-forming sheet is moved via a conveyer path. The image forming sheet is a pressure/temperature-sensitive sheet or a temperature-sensitive sheet. The thermal heads are moved in the line-printing direction. Adjacent-opposing ends of adjacent thermal heads are separated in the line-printing direction, and overlap in the transport direction. The thermal heads are controlled so as to simultaneously generate image-pixels on the image-forming sheet. The printing speed is high due to a plurality of colors being simultaneously printed. The thermal heads are used as part of pressure applying unit. The pressure applying unit is provided for selectively applying predetermined pressure to the micro-capsules, when the image-forming sheet is a pressure/temperature-sensitive sheet. The thermal heads can also be applied to a high-speed printing of a mono-chrome image on the temperature-sensitive sheet.

    摘要: A thermal printer that forms an image on a sheet. The thermal printer includes a thermal head having a plurality of linearly arranged thermal elements, a device for converting image information into bit-map image data, and a device for storing the bit-map image data. A predetermined portion of the stored bit-map image data is transmitted to the thermal head, and a remaining amount of the stored bit-map image data which has not been transmitted to the thermal head is detected. A time interval between a transmission of the predetermined portion of the stored bit-map image data and a subsequent transmission of the predetermined portion of the stored bit-map image data is set, in response to the detected remaining amount of the stored bit-map image data.

    摘要: In an image forming apparatus, a developing device is disposed adjacent to a belt-like photosensitive member. A rotary type developing device has a hollow cylindrical casing rotatable around a shaft having a central portion for rotation. The developing device includes a casing which is rotated in a predetermined direction, and four partitions which divide the casing to make four developing units which extend radially outward from the shaft. A toner storing section or hopper is provided on one side of the developing device, i.e., on a front side of the image forming apparatus, and a toner cartridge is detachable from a top of the hopper, and the toner cartridge is exchanged when an end signal of the toner is detected by a sensor in the casing. The toner hopper is filled by new toner from the toner cartridge, and the toner is carried by conveyor members, which control an amount of the toner in the casing, and a supply roller supplies the toner to a developing roller. Therefore, the device supplies a required amount of toner to a toner supply roller and a developing roller at all times. This provides an image forming apparatus with a great freedom of layout which needs a minimum sectional space relative to a photoconductive element and which, therefore, has a miniature configuration. Also, if amounts of transport of first and second conveyor members are adequately selected, a uniform developer distribution in a longitudinal direction without resorting to a complicated control is insured.
