Claim 9:
10. The fixing belt according to claim 6,
wherein, assume that (i) a cross section of the sliding layer is obtained by cutting the sliding layer along the thickness direction of the sliding layer serving as a vertical axis and is divided into a plurality of sections each having a width whose value is the same as a value of the thickness of the sliding layer in a direction perpendicular to the thickness direction, and (ii) a ratio of an area of the filler to an area of the sliding layer in each of the plurality of sections of the cross section is an area ratio,
wherein a period coefficient is calculated using a formula (Ave %−Min %)/Ave %, where an average of area ratios of areas of the filler in all sections of the plurality of sections is Ave % and a minimum of the area ratios is Min %, and
wherein a value of the calculated period coefficient is 0.6 or more.
