Abstract
An image forming apparatus includes an image carrier, a developing roller, a biasing member, and a fluctuation preventing member. A latent image is formed on the image carrier. The developing roller is provided to face the image carrier and develops the latent image on the image carrier. The biasing member is provided on an outside of an end portion of the developing roller and biases the image carrier and the developing roller in a direction where the image carrier and the developing roller approach each other. The fluctuation preventing member is interposed between the image carrier and the developing roller and prevents, along with the biasing member, a fluctuation in a distance between a surface of the developing roller and a surface of the image carrier in a region where the image carrier and the developing roller face each other.
