Abstract:
A developing device includes a container, a toner holding member, a developing electric field forming unit, a layer forming unit, an electrode member, and a low-frequency electric field forming unit. The container accommodates toner. The toner holding member holds toner and transports the toner to a developing region where the toner holding member and the latent image holding member face. The developing electric field forming unit forms a developing electric field for developing a latent image held on a latent image holding member. The layer forming unit forms a toner layer on the toner holding member prior to the developing region. The electrode member faces the toner holding member. The low-frequency electric field forming unit forms a low-frequency electric field acting on residual toner between the electrode member and the toner holding member, and forms stripe-shaped projections in accordance with a period of the low-frequency electric field.
