摘要： An image forming apparatus develops a latent image formed on an image carrier with a developer that forms a magnet brush on a developer carrier. The developer carrier is made up of a sleeve and a stationary magnet roller accommodated in the sleeve. The magnet roller includes a main pole for causing the developer to form the magnet brush and auxiliary poles for helping the main pole exert a magnetic force. An electric field including an oscillation component is formed between the image carrier and the developer carrier. A particular ratio is set up between a distance between the image carrier and the developer carrier, as measured at the boundary of a nip, and the shortest distance between them, between the above shortest distance and the shortest distance between the developer carrier and a metering member, or between the shortest distance between the image carrier and the developer carrier and the amount of developer scooped up to the image carrier.

摘要： An image forming method including providing a developer including a toner and a magnetic carrier, a developer carrier configured to convey the developer deposited thereon, and magnetic field generating means fixed within the developer carrier, and forming a magnetic field which forms a magnet brush between the image carrier and the developer carrier such that the magnet brush rises, contacts the image carrier and collapses within a range in which the magnetic field is more intense than an electric field capable of separating the toner and the magnetic carrier from each other by using the magnetic field generating means. The magnetic brush rubs the image carrier to thereby develop a latent image formed on the image carrier.

摘要： An image forming apparatus includes an image support which supports an electrostatic latent image on a surface of the image support. A developing unit has a developing agent support which retains a developing agent, including a toner and carriers, contained in the developing unit. The developing unit converts the latent image on the image support into a toner image by causing the toner to adhere to the surface of the image support. A developing bias supplying unit supplies a developing bias voltage to the developing agent support of the developing unit, the developing bias voltage being one of a DC bias voltage and an AC bias voltage. A timer measures a non-driven period of the developing agent in the developing unit. A control unit selects one of the DC bias voltage and the AC bias voltage from the developing bias supplying unit based on the non-driven period measured by the timer, and controls the developing bias voltage at an output of the developing bias supplying unit such that the selected one of the DC bias voltage and the AC bias voltage is supplied to the developing agent support.
