发明名称 Image forming apparatus
摘要 An image forming apparatus includes a plurality of image carriers, a plurality of developing units configured to contact each of the plurality of image carriers to develop a latent image formed on each of the plurality of image carriers, a contact and separation unit configured to perform contact and separation of the plurality of image carriers and the plurality of developing units, a drive unit that drives the contact and separation unit, and a control unit that controls a drive speed of the drive unit so that the plurality of developing units are separated from the plurality of image carriers after the development performed by the plurality of developing units is completed, and the control unit controls the drive speed so that a last developing unit is separated after completion timing of development performed by the last developing unit and before separation timing of the last developing unit.
