Abstract
A fixing belt includes: a base having an endless shape; and a resin layer covering a surface on an inner peripheral side of the base, the resin layer comprising a resin and a filler, and having a second surface opposite to a first surface facing the base, the second surface having cell structures, and being roughened with the filler. When arithmetic mean roughnesses of the second surface in the central region X and the end regions Y and Z are defined as RaX, RaY and RaZ respectively, a difference between RaX and RaY, a difference between RaY and RaZ, and a difference between RaX and RaZ are all 0.1 μm or smaller, and a coefficient of variation of areas of the cell structures contained in each of the central region X, and end regions Y and Z is 25% or smaller.
