Abstract:
1. A developing unit that transports toner for supplying the toner onto a surface of a toner carrying member by a toner supplying unit, while causing the toner to hop on the surface of the toner carrying member using an electric field, to a developing area that is an area opposite the toner carrying member and a latent-image carrying member, that causes the hopped toner to adhere to a latent image on the latent-image carrying member in the developing area, and that develops the latent image, the developing unit comprising: a brush member that includes a base member, a plurality of raisings that are erected on a surface of the base member, and a touching member, wherein the brush member traps toner within the raisings and the touching member causes a flicker movement in the raisings of the brush member so that the toner trapped within the raisings is shaken and flown due to the flicker movement to the surface of the toner carrying member, the touching member disposed above the rotational axis of the toner carrying member with respect to the ground.
