A toner supply system having: a receiving section that is set in a body of an image forming apparatus so as not to rotate; and a substantially cylindrical toner container that is mountable in and dismountable from the receiving section and that can be driven to rotate on an axis while being mounted in the receiving section, wherein: the toner container has a first toner feeder for feeding toner stored therein toward the receiving section while the toner container is rotated; and the receiving section has a supply port that permits toner fed thereto with rotation of the toner container to drop down and a toner stirrer that extends to a position close to the first toner feeder located inside the toner container while the toner container is mounted in the receiving section.

Toner supply system including receiving section having toner stirrer and toner container rotatble in toner supply system

Disclosed is a production method of an electrophotographic toner, which comprises toner particles comprising a resin and a colorant. The method comprises a step of forming toner particles in an aqueous medium, and processing an aqueous medium containing the toner particles or a component of the toner particles by gas bubbles.

Preparation method of toner and toner

An apparatus for producing toner for developing an electrostatic latent image, is provided with an inlet section to receive a slurry containing toner particles, impure fine particles having a specific gravity smaller than that of the toner particles and aqueous medium; a centrifugal concentrating device for applying centrifugal force to the slurry and having a precipitating plate with which the toner particles are precipitated from the slurry and an accommodating section to accommodate a concentrated slurry containing the precipitated toner particles, and

Production apparatus of toner for developing electrostatic images, production method thereof, and toner for developing electrostatic images

A toner for developing an electrostatic latent image is disclosed. The toner comprises a resin, a colorant and a releasing agent or a crystalline polyester compound, and the toner has crushability index from 0.1 to 0.8. The toner is preferably produced by sat-out/fusion-adherence of a composite resin particle and a colorant particle, the composite resin particle comprises polyester compound in a portion of the composite resin particle other than outermost layer

Toner and image forming method

Disclosed is a toner for developing an electrostatic latent image, comprising colored particles containing a colorant and a binder resin, and fine particles, wherein said fine particles have a releasing index of 10 to 50 in terms of a turbidity.
