Abstract: An image forming apparatus includes a plurality of image forming units for forming an image on a printing medium such as a sheet of paper. A plurality of color types of toner are arranged on a transport path of the printing medium. Toner images corresponding to the color types of toner are color-by-color transferred onto the printing medium. Light emitted from a flash lamp melts and fixes the toner images. The fixing order of the toner images corresponding to the color types of toner is decided so that the toner images are fixed in ascending order of toner's absorptivity of the light emitted from the flash lamp or in descending order of toner's reflectivity of the light.

Abstract: This invention relates to image formation toner, 2-component developer, image formation method and method for manufacturing image formation toner, for preventing clogging of the filter. Toner is used in which the ratio of the component measured by GPC to have a molecular weight between 500 to 1000 is 10 parts by weight or less with respect to 100 parts by weight of the entire toner. Since the case of clogging of the HEPA filter is the 500 to 1000 molecular weight component, clogging of the filter is prevented by reducing this component.

Abstract: Disclosed is an image forming apparatus for forming an image on a sheet. The image forming apparatus comprises a unit for forming a toner image on the sheet and a flash fixing unit for fixing the toner image onto the sheet by an emission of light from a flash lamp. The flash fixing unit includes a first unit having a first flash lamp disposed at the center and a second unit having second flash lamps disposed on both sides of the first flash lamp and exhibiting a light emitting energy larger than a light emitting energy of the first unit. The second flash lamps disposed at a pitch smaller than the pitch at which the first lamps are disposed. With this construction, the fixing energies at both ends of the flash fixing unit increase, and the fixing energy at the center decreases. It is therefore possible to prevent an ill-fixed state and improve a fixing efficiency.

Abstract: 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.

Abstract: An improved apparatus and method for fusing images of pigmented thermoplastic resin marking particles to a receiver member. A marking particle image on the surface of a receiver member contacts the peripheral surface of a hollow member. A source of radiant energy, capable of at least partially melting such particles, is mounted within the hollow member. The hollow member is transparent to the energy of the source. The entire image-bearing surface of the receiver member is simultaneously pressed into full and intimate contact with the peripheral surface of the hollow member in order to lower the particle/receiver member boundary thermal resistance and enhance particle flow during radiation of energy by the source to fuse the image to the receiver member.

Abstract: Fusing both small and large image areas of dry resinous marking particles supported on the surface of a receiver member by irradiating the particles with energy to at least partially melt the particles at the interface between the particle and receiver member. Fusing is accomplished by directing the energy from an energy source toward the surface of the particle-supporting receiver member along a path having a major low-angle component relative to the receiver member. The particles are irradiated over a substantial portion of their surface area, with energy which is not reflected by the receiver member and with energy which has been reflected by the receiver member. A sufficient amount of energy is thus received to at least partially melt the particles at the interface between the particle and receiver member so that the particles adhere to the receiver member.

Abstract: The flash discharge lamp is energized by the discharge of a battery of flash condensors. When an attempt is made to gain access to the flash condensors, these are automatically and quickly discharged through current-limiting resistors, to preclude the danger of electrocution. The fixing station of the copying machine, including the flash discharge lamp, the battery of flash condensors, the transport rollers which transport copying medium through the fixing station and almost all of the electronic control circuitry of the fixing station, are provided on a single housing, removable from the copying machine as a pull-out unit.
