    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 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.

    摘要： To provide an image forming device that is capable of preventing deterioration of the image quality through preventing deterioration of the toner even if frequency of making a copy is low.The image forming device includes: a developing part 44 having a developing roller 443 for achieving development by electrostatically attaching a toner onto an electrostatic latent image formed on a photoreceptor 41; a transferring part 46 for transferring a developed toner image to a paper; and a cleaner part 47 for removing and collecting the toner remained on the photoreceptor 41 after transferring, wherein the developing roller 443 is rotary-driven at a lower speed than a speed of development under a standby state. The image forming device includes a standby-state refresh control part 240 for forcibly consuming an amount of the toner that is calculated based on accumulated time of the low-speed rotary drive.
