Abstract
A service unit for an electrographic apparatus has a reservoir for storage of fresh toner or developer and a reservoir for storage of waste or depleted toner or developer. The fresh toner reservoir is separable from the waste toner reservoir and detachable from the service unit. The fresh toner reservoir has a wall which, in use, is in contact with a wall of the waste toner reservoir. Both contacting walls are flexible whereby the combined volume of the two reservoirs is less than the sum of the volumes which may be used to store the fresh and waste toner at different stages in the duty cycle of the service unit.
