Abstract
An image forming apparatus includes an image forming unit, a developer carrier, a transfer part, a fuser, a temperature detecting part and a control part that rotates the developer carrier in the predetermined direction when a latent image is developed and in an opposite direction when an apparatus inner temperature detected by the temperature detecting part is equal to or higher than a glass transition starting temperature. The glass transition starting temperature is determined in consideration of a differential scanning calorimetry (DSC) curve of the toner.
