Abstract
There is provided a developing apparatus which, when using a conveying member having a resin-made rotation shaft member, is capable of preventing fusion and adhesion of a toner in a vicinity of a bearing resulting from friction between the rotation shaft member and the bearing. A developing apparatus includes a developing tank; a first developer conveying section and a second developer conveying section; a first bearing and a second bearing; a first temperature rise suppression section and a second temperature rise suppression section which a have higher thermal conductivity than those of a first rotation shaft member and a second rotation shaft member as well as those of the first bearing and the second bearing; and a deflection suppression belt which is stretched out by the first temperature rise suppression section and the second temperature rise suppression section.
