摘要： A control part 33 rotates a developer roller 21a at a second rotation speed, which is slower than a normal rotation speed during an image formation period (first rotation speed), during a non-image formation period while a heater 14 is in use. This prevents deformation of the developer roller 21a caused by radiant heat from a photoconductive drum 41, effectively prevents the appearance of image fogging, concentration unevenness, and the like, and also suppresses toner deterioration in a development unit 21.

摘要： A developing device (50) includes a developing sleeve (53) for supplying toner particles (T) to a latent image area (22) on a peripheral surface of a photoconductive drum (20) while rotating about a central shaft (534). The developing sleeve (53) has an immovable sleeve magnet (533) therein. Two magnetic members (82) are disposed in opposite end portions of the developing sleeve (53) and are spaced a predetermined distance from the peripheral surface of the developing sleeve. Each magnet member (82) has an arc shape. A magnetic member magnet (83) is mounted in the magnet member (82) and faces a sleeve magnet (533) so that opposite facing portions of the magnetic member magnet (83) and the sleeve magnet (533) have the same polarity. With this construction, toner particles are prevented from leaking from the end portions of the developing sleeve (53).

摘要： A housing of a developing device has a circulating conveyance passage with a front conveyance passage along a developing roller and a rear conveyance passage parallel to the front conveyance passage. Front and rear spiral feeders are provided in the front and rear conveyance passages for conveying developer particles. The housing has a first developer inlet opening for receiving developer particles from a developer supplier and a second developer inlet opening for receiving recycled developer particles. The rear spiral feeder includes a conveyance power reduction portion at a position downstream from the first and second developer inlet openings and locally reduces conveyance power. The first and second developer inlet openings upstream of the conveyance power reduction portion and are where developer particles are likely to be upwardly surged due to the rotation of the rear conveyer.

摘要： A developing device includes a developing sleeve for supplying toner particles to a latent image area on a peripheral surface of a photoconductive drum while rotating about an axis. The developing sleeve has a permanent magnet therein. Two magnetic members are provided in the developing device and face opposite ends of a peripheral surface of the developing sleeve at a predetermined distance from the developing sleeve. The magnetic members have arc-shaped inner surfaces. A blade is spaced a predetermined distance from a central portion of the peripheral surface of the developing sleeve. The blade adjusts the amount of toner particles supplied to the photoconductive drum. The gap between the arc-shaped inner surface of the magnetic member and the peripheral surface of the developing sleeve gradually increases from upstream to downstream in a rotational direction of the developing sleeve.

摘要： A grid wire cleaning mechanism is provided to prevent a reduction in image quality due to the surface of the electrostatic latent image carrier not being uniformly charged as a result of corona products adhering unevenly to the surface of the grid wires to extend the life of the grid wires and grid wire contact member. A first abrading member 71 abrades grid wires 224. A movement device 73 moves the first abrading member 71 in the same direction as the direction of extension of the grid wires 224. A humidity measurement unit 741 measures the humidity near the grid wires 224. The operation control unit 743 operates the movement device 73 when cleaning the grid wires 224, but does not operate the movement device 73 when the humidity measured by the humidity measurement unit 741 exceeds a predetermined threshold value.
