Abstract
An image forming apparatus, laving a photosensitive member, an exposure device to form an electrostatic latent image on the photosensitive member, a developer roller to supply a developer agent to the photosensitive member, a humidity sensor to detect humidity, and a controller, is provided. The controller executes a preparatory rotation controlling process, in which the photosensitive member and the developer roller are rotated prior to forming the electrostatic latent image, and an image-forming controlling process, in which the electrostatic latent image is formed on the photosensitive member. In the preparatory rotation controlling process, the developer roller is rotated at a first peripheral velocity under a condition of the humidity being lower than or equal to a predetermined value, and at a second peripheral velocity being higher than the first peripheral velocity under a condition of the humidity being higher than the predetermined value.
