摘要： An image forming apparatus, using a developer including toner particles and carrier particles, includes a developing unit, a cleaning unit, and a conveying unit. The developing unit contains the developer and develops an electrostatic latent image formed on an image carrying member as a toner image with the toner particles. The cleaning unit contains the developer and mixes the developer with the toner particles collected from the image carrying member after transferring the toner image. The conveying unit conveys a mixture of the collected toner particles and the developer from the cleaning unit to the developing unit.

摘要： An image forming apparatus of the present invention includes a developing unit for developing a latent image formed on an image carrier with a two-ingredient type developer, i.e., a toner and carrier mixture. A toner replenishing device replenishes toner stored in a toner storing portion to the developing unit. A carrier storing portion, storing a carrier therein, is constructed independently of the toner storing portion. The carrier is fed from the carrier storing portion to the developing unit by a toner conveying force available with the toner replenishing device.

摘要： A developing method of the present invention uses a sleeve accommodating a stationary magnet roller formed with a plurality of magnetic poles and facing an image carrier. The sleeve is rotated to convey a developer, which is made up of toner grains and magnetic carrier grains and deposited on the sleeve, to a developing zone for thereby feeding the toner grains from a magnet brush formed by the developer to a latent image formed on the image carrier. When the developing zone is seen from the image carrier side, the ratio of the total area of voids present at the tips of the magnet brush to the total area of the developing zone is selected to be 25% or less.
