A removable, sealable, magnet-less cartridge for use in a reproduction apparatus of the type having a control device to control the apparatus, a photoreceptor to receive toner through a photoreceptor path and to transfer the toner onto imaged portions of the photoreceptor, and a developer transporter of the magnetic type to carry toner in a magnetic brush to the imaged portions of the photoreceptor and to return unspent toner therefrom. The magnet-less cartridge device has a housing adjacent to the developer transporter; a developer mix hopper and a mixer within the housing for holding and mixing toner and a carrier therefor in the form of a developer mix; a scraper at an open end of the housing in communicating adjacency of the developer transporter; and a sealing device including a first movable sealing member, a second movable sealing member, each of which are adjacent to the open end of the housing and in operational communication with the control means to seal the cartridge in a plurality of sealing modes.
