摘要： A developing device using a one-component developer composed of toner particles, which device comprises a vessel for holding the developer, and a developing roller rotatably provided within the vessel so that a portion of the roller is exposed therefrom and faces a surface of an electrostatic latent image carrying body to form a developing area. During a rotation of the roller, the toner particles are entrained by a surface of the roller to form a developer layer therearound, and are carried to the developing area for a development of an electrostatic latent image formed on the latent image carrying body. The roller and the latent image carrying body are reversely rotated such that the surfaces thereof move upward at the developing area. A blade member is provided within the vessel and resiliently engaged with the roller for regulating a thickness of the developer layer, and is disposed below the roller to prevent a leakage of the toner particles from the vessel at an underside of the developing roller.

摘要： An electrophotographic recording apparatus comprising a rotatable photosensitive drum (1) and unit (3) for electrifying the drum, depositing an electrostatic latent image on the drum, developing the latent image, transferring the image on the drum to printing paper (PP), and optical-deelectrifying the drum. In this method, the optical deelectrification unit (6) is located at a position opposite to the drum (1) with respect to a passage of the printing paper (PP) and an optical deelectrification beam is irradiated to the drum only when the printing paper interrupts an optical path of the deelectrification light toward the drum.

摘要： A developing unit is used for for supplying a developer to a photosensitive body (11) for visualizing an electrostatic image on the photosensitive body into a toner image. The developing unit comprises a developer hopper (1) for accommodating the developer which includes a toner and carriers which are magnetic, a rotatable developing roller (2) for supplying the developer within the developer hopper and comprising an inner magnet roll (2a) and a non-magnetic outer sleeve (2b) which has a peripheral surface on which the developer is carried, a doctor blade (3, 3A, 3B) which is provided in a vicinity of the developing roller and forms a predetermined gap between the peripheral surface of the outer sleeve so that a thickness of the developer on the peripheral surface of the outer sleeve is restricted to a predetermined thickness, and a carrier accumulating part (4, 4A, 4B) provided in a vicinity of the doctor blade on an upstream side of a direction in which the developer within the developer hopper generally flows. The carrier accumulating part interacts with the inner magnet roll of the developing roller and forms a magnetic field between the inner magnet roll, so that a developer accumulation formed in a vicinity of the doctor blade has a carrier concentration higher than that at other parts within the developer hopper.
