Abstract
A disclosed development device includes: a latent image carrier; a conveying member disposed so as to face the latent image carrier, the conveying member having plural electrodes insulated from one another and arranged at predetermined intervals so as to generate an electric field for moving toner on the conveying member; a voltage application unit applying a voltage of n phases (n is a positive integer not less than one) to the electrodes so as to form a cloud of the toner and the toner is adhered to the latent image carrier so as to form a visualized toner image; a toner supply unit supplying the toner to the conveying member; and a height adjusting member adjusting a uniform height for a toner layer of the toner immediately before a development area on the conveying member in which development is performed.
