| 20080311503 | Toner, method of manufacturing the same, two-component developer, developing device, and image forming apparatus - A toner composed of small particles excellent in a cleaning property, a transferring property, and charge uniformity is provided as well as a method of manufacturing the toner, and two-component developer, developing device, and image forming apparatus using the toner. The toner contains binder resin and colorant, and includes a particle which has an outline having one or more and three or less bending points in its projection image on a plane. The toner thus contains a non-spherical particle and therefore is caught easily by a cleaning blade as well as coming into point-contact with a to-be-transferred member, therefore being capable of having both of cleaning property and transferring property. | 12-18-2008 |

| 20100047707 | METHOD FOR PRODUCING TONER - A toner which can efficiently induce high-frequency magnetic induction heating by Neel relaxation and/or Brown relaxation is provided. A toner including a core particle containing a thermoplastic polymer material and superparamagnetic ferrite fine particles having a particle diameter of less than 100 nm which adhere to the surfaces of the core particle is manufactured by directly forming the superparamagnetic ferrite fine particles having a particle diameter of less than 100 nm on the surfaces of the core particle so that the superparamagnetic ferrite fine particles having a particle diameter of less than 100 nm are not in contact with each other. As a result, the toner is prevented from being scattered due to the influence of a magnetic field, so that a high quality image is formed. | 02-25-2010 |
