An image forming apparatus includes: an image bearing member; a development device that includes a developer bearing member in a development position opposite to the image bearing member to develop an electrostatic latent image formed on the image bearing member, the developer bearing member bearing and conveying a developer; a bias applying portion that applies a development bias to the developer bearing member; a recording-material sensing portion that senses a type of a recording material to which a toner image developed by the development device is transferred; and a controller that controls the bias applying portion to apply the development bias that degrades a development characteristic when the recording material has low smoothness, compared to high smoothness, from a sensing result of the recording-material sensing portion.
