Abstract
A belt driving apparatus is configured so as to satisfy a relationship μ1(2T sin(θ1/2)+f1)<μ2(2T sin(θ2/2)+f2), wherein μ1 is a dynamic friction coefficient between the supporting roller and the endless belt, μ2 is a dynamic friction coefficient between the steering roller and the endless belt, θ1 is a winding angle of the endless belt with respect to the supporting roller, θ2 is a winding angle of the endless belt with respect to the steering roller, f1 is the first external force applied to the supporting roller through the endless belt, f2 is the second external force applied to the steering roller through the endless, and T is a tension force applied to the endless belt by the tension roller.
