A development device configured to develop an electrostatic latent image on an image carrying member with a two-component developer having a toner and a carrier, the development device including: a developer carrying member to carry the two-component developer to a development region in which the developer carrying member faces the image carrying member; a developer control member to control a volume of the two-component developer; a plurality of electrodes to be separately disposed in a direction parallel to a rotation axis of the developer carrying member while separated from a surface of the developer carrying member and located between the developer control member and the development region in a rotation direction of the developer carrying member; and a power source to apply a power to the plurality of electrodes to form a periodically changing electric field generating an external force to convey the two-component developer in the rotation axis direction.
