Patent ID: 8712271

Claim:
An image forming apparatus comprising: an image forming portion configured to form a toner image on a recording material using toner containing a wax component; a fixing portion configured to fix the toner image on the recording material, said fixing portion including a heating rotatable member configured to heat the toner image on the recording material at a nip portion, a pressure rotatable member configured to form the nip portion cooperatively with said heating rotatable member, and a cooling portion configured to cool said pressure rotatable member; and a controlling portion configured to control an operation of said fixing portion, wherein said controlling portion controls a cooling condition of said cooling portion so that a temperature of said pressure rotatable member is kept at a first temperature lower than a second temperature at which an endothermic amount of the toner indicates a main peak, and wherein said controlling portion controls a fixing condition of said fixing portion so that an interfacial temperature between a toner layer and the recording material becomes a temperature that is lower than a temperature of an outermost surface of the toner layer when the temperature of the outermost surface of the toner layer reaches the second temperature in the case that the toner image having a maximum toner amount per unit area is formed.
