An image forming apparatus includes a toner conveyance device and a controller. The toner conveyance device includes a casing, a screw and a film. The casing has a toner conveyance path. The screw rotates in a first rotational direction to convey a toner stored in the toner conveyance path in a predetermined conveyance direction. The film is attached to the screw and rotating together with the screw while coming into contact with an inner face of the toner conveyance path to be elastically deformed. The controller executes a toner conveyance control to rotate the screw and the film in a first rotational direction and a reverse rotation control to rotate the screw and the film in a second rotational direction opposite to the first rotational direction.
