An image formation device provided with: a development member that supports a developer for forming a toner image on an image carrier; a cleaning member, which abuts against the development member, for removing residual developer from the development member; a conveyance member, provided in contact with the development member, for conveying supplied developer to the development member; and an actuation unit that controls actuation of the conveyance member and/or the development member. Before a main actuation performed when forming an image, the actuation unit performs preliminary actuation of the development member and the conveyance member for a given amount of time with the supply of the developer to the conveyance member stopped, thereby minimizing developer consumption or degradation during the preliminary actuation while eliminating warpage of the development member or the conveyance member, which are formed from elastic members.
