Zusammenfassung:An image forming apparatus includes an image bearing member, an intermediate transfer belt, and a contact member. The intermediate transfer belt includes a base layer, a surface layer formed on an outside of the base layer, and an inner surface layer formed on an inner side of the base layer. A position at which the contact member and the intermediate transfer belt contact is arranged on a downstream side of the intermediate transfer belt in a rotation direction of the intermediate transfer belt. Rv>Rs1 and Rs2>Rs1, and Rs2/Rv≤40 are satisfied where Rv(Ω) is a volume resistance value of the intermediate transfer belt in a thickness direction, Rs1(Ω) is a first surface resistance value of the inner surface layer side in a surface direction, and Rs2(Ω) is a second surface resistance value on the surface layer side in a surface direction.
