Abstract
A fixing belt is heated by a heater in contact with an inner circumferential face through a lubricant while rotating about an axis. The fixing belt includes: a belt body formed in a tubular shape; a plurality of oil repellent portions formed on an inner circumferential face of the belt body, each having a surface free energy lower than that of the lubricant to repel the lubricant; and a plurality of oil nonrepellent portions formed on the inner circumferential face of the belt body, each having a surface free energy higher than that of the lubricant to hold the lubricant. The oil repellent portions and the oil nonrepellent portions extend in a circumferential direction of the belt body and are alternately arranged in an axial direction of the belt body.
