IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD |
摘要 |
An image forming apparatus includes plural developing units separately containing a toner A and a toner B that satisfy relationships (1) and (2) and have similar colors. The toner A and the toner B each contain a binder resin containing a polyester about 90 mass % or more of the binder resin, and about 90 mass % of the binder resin of the toner A and about 90 mass % of the binder resin of the toner B are the same resin. The polyester contains an amorphous polyester having an alkyl side chain and a crystalline polyester. The relationship (1) is Ta (toner A)>Tb (toner B) in terms of flow tester ½ effluent temperature. The relationship (2) is Aa (toner A)>Ab (toner B) in terms of an amount of an aluminum (with reference to net intensity) measured with fluorescent X-ray. |
