TONER FOR IMAGE FORMING, IMAGE FORMING METHOD AND IMAGE FORMING DEVICE

Title:

TONER FOR IMAGE FORMING, IMAGE FORMING METHOD AND IMAGE FORMING DEVICE

Document Type and Number:

Japanese Patent JP2002169322

Kind Code:

A

Abstract:

To provide image forming toner, an image forming method and an image forming device by which sufficient low-temperature fixing property is obtained, a sleeve is not stuck to a non-image part even in the case of repetitive use, and high image quality without irregular image density, the lowering of image density nor fogging is obtained.

Toner for electrostatic charge development incorporates at least binding resin, a colorant and a releasing agent, and the volume average particle size of the toner measured by a colter counter is 5 to 8 μm and the content rate of ≤5 μm fine is 60 to 75 number % and the content rate of particles whose equal diameter of the circle of number reference measured by a flow type particle image analyzing device is 0.6 to 3 μm is ≤25%.
