Abstract
An image forming apparatus includes an image forming section, a transferred member, a transfer roller, and a separator. The image forming section forms a developer image. The transferred member is conveyed in a first direction and the developer image is to be transferred on the transferred member. The transfer roller faces the transferred member, and makes a transition between a biasing state in which the transferred member is biased by the transfer roller and a separated state in which the transfer roller is separated away from the transferred member. The separator starts to separate a medium away from the transferred member after the transfer roller starts making a transition from the biasing state to the separated state, the medium being held between the transferred member and the transfer roller in the biasing state.
