Patent ID: 7884840

Claim:
An image forming apparatus, comprising: a first image carrying member configured to carry a first toner image, formed with a toner, on a surface of the first image carrying member, a first transfix unit, comprising: a first heater; and a first heatable member, heated by the first heater, configured to receive the first toner image from the first image carrying member with heat generated on the first heatable member and configured to transfer and fix the first toner image onto a first face of a recording sheet with the heat generated on the first heatable member; a second image carrying member configured to carry a second toner image, formed with a toner, on a surface of the second image carrying member; a second transfix unit, comprising: a second heater; and a second heatable member, heated by the second heater, configured to receive the second toner image from the second image carrying member with heat generated on the second heatable member and configured to transfer and fix the second toner image onto a second face of the recording sheet with the heat generated on the second heatable member surface layers of the first and second heatable members have a heat resistance which is greater than a heat resistance of the first and second image carrying members, and the first and second image carrying members have a toner separation property which is greater than a toner separation property of the surface layers of the first and second heatable members.
