Abstract
An image forming apparatus capable of forming an image includes an image bearing member on which an electrostatic latent image is to be formed, a developer carrying member for carrying a developer to visualize the electrostatic latent image, and a developer feeding member, having a foam layer at its surface, for feeding the developer to the developer carrying member by being rotated in contact with the developer carrying member. In addition, a controller is capable of executing an operation in a first mode in which the developer feeding member is rotated for a first time and then the electrostatic latent image is visualized at a first speed by the developer carrying member and an operation in a second mode in which the developer feeding member is rotated for a second time longer than the first time and then the electrostatic latent image is visualized at a second speed slower than the first speed by the developer carrying member.
