A conveyer device includes a container containing a toner therein and having a bottom wall and two side walls, a toner discharge port formed in the bottom wall, and a conveyance mechanism for conveying the toner in the container toward the discharge port. The conveyance mechanism includes a rotary shaft that is supported across both side walls to rotate and is positioned to pass above the discharge port, and a pair of spiral vanes formed on the rotary shaft. The vanes have their spiral directions opposite to each other. The discharge port has a first side edge and a second side edge opposed to each other at a distance in the axial direction of the rotary shaft. One of the spiral vanes extends from the first side edge toward the second side edge of the discharge port, above the toner discharge port. The other spiral vane extends from the second side edge toward the first side edge of the discharge port.

Flash fixing equipment for fixing a toner image onto a medium by means of flashlight is to reduce non-uniformity of halftone image print density. Flash fixing unit has flash energy distribution consisting of a center zone and front/end zones. The flash frequency of the flash lamp is controlled so that the toner fixing start energy being subtracted from the added value of flash energies of front and end zones becomes substantially equal to the flash energy value on the center zone. The energy distribution exceeding the fixing start energy which affects print density (size of toner-overflowed area) is controlled to have a flat characteristic to reduce non-uniformity of print density.

A fixing device includes a radiating portion that radiates light on a recording medium on which a toner image is formed and that is transported along a transport path, a partition member that transmits the light radiated from the radiating portion and partitions between the radiating portion and the transport path, and a drive section that moves a scraping member scraping toner that adheres to the partition member and is heated by the radiation of the light from the radiating portion so as to contact a surface of the partition member of the transport path side.

A flash fixing device comprises a first and second flash lamps that emit flashes of light that fix a toner image transferred onto a recording medium and a light emission control unit that controls the light emissions of the first and second flash lamps so that the light flashes emitted from the first flash lamp and the second flash lamp are each irradiated at different timing on each portion on the recording medium.

A sealing mechanism for preventing the leakage of powder from between a through-hole and a rotary shaft which is supported between one side wall of a container containing said powder and the other side wall thereof and of which one end protrudes outwardly beyond said through-hole formed in said one side wall. A circular flange is formed on the rotary shaft, and a seal ring member is fitted between the circular flange of the rotary shaft and said one side wall. A to-be-engaged groove is formed in one end of the rotary shaft. An input gear made of a synthetic resin is fitted to the one end of the rotary shaft, and an engaging projection that engages with said to-be-engaged portion is formed in a portion of the input gear that is fitted to the rotary shaft.

A toner cartridge including a container having a toner discharge port, a toner contained in the container and a stirrer for stirring the toner existing in the container. The stirrer includes a rotary shaft rotatably mounted between both side walls of the container, not less than two arms extending in the radial direction, from the rotary shaft at fixed intervals in the axial direction and not less than one paddle disposed between the ends of the arms. Each paddle has a plate piece made of a synthetic resin film extending in a direction to separate away from the rotary shaft. The plate piece has one or more holes formed therein.

摘要:
A new flash fixing device configured to fix a toner image by a flash light is presented. This flash fixing device includes a plurality of flash lamps arranged parallel to each other, and a reflection board including a plurality of side part reflection surfaces each facing from a side to the respective flash lamps. In a case where a surface including two central axes of the two flash lamps arranged one at each end is defined as a standard surface, an acute angle against the standard surface is set to be decreased as the side part reflection surface is positioned closer to a center of the arrangement of the plurality of the flash lamps.
