  • Patent number: 7389067
    Abstract: A developer cartridge is constituted to be mounted attachably and detachably in a directional orthogonal to a rotating shaft of a developing unit main body and the developer cartridge has a developer containing portion and a developer recovery portion for recovering used developer from the developing unit. A supply port opens to supply the developer from the developer containing portion and a recovery port opens in the developer recovery portion to recover used and recovered developer. A supplying opening portion is formed in a shutter member at a position corresponding to the supply port and a recovering portion is formed in the shutter member at a position corresponding to the recovery port. The shutter member opens and closes both the supply port and the recovery port.

  • Patent number: 6253051
    Abstract: A wet-type image forming apparatus which allows excess solvent to be effectively removed from the developed image is disclosed. A developing roller develops a latent image on the photoconductor member using the liquid developer composed of toner particles and a solvent. A squeezing roller squeezes excess solvent from a surface of a photoconductor member. A heater heats liquid developer existing on the photoconductor member to a temperature at which the solvent of the liquid developer is prone to vaporize. The heater is provided in one of the developing roller, the squeezing roller, and the liquid developer reservoir.
