Abstract:
There is provided a development system comprising a developer carrier member that carries a developer, a developer supply roller that supplies the developer carrier member with the developer, a developer container that stores the developer, a toner compression roller that contacts with the developer carrier member and presses toner against the developer carrier member, the toner included in the developer and a density sensing unit that senses a density of the toner in the developer in the developer container. A condition for the toner compression roller is changed depending on the density of the toner in the developer in the developer container or depending on a type of a recording medium.
