An apparatus includes a developer and a photoreceptor, where the developer is to transfer a toner to the photoreceptor. The apparatus includes a housing that is moveable in an image forming device, and an actuator assembly engaged with the housing. The actuator assembly is actuatable between different states in response to control by the image forming device during an image forming operation of the image forming device, where a first state of the different states corresponds to the housing being at a first position that disrupts a transfer of the toner to a transfer member of the image forming device during the image forming operation, and a second state of the different states corresponds to the housing being at a second position that allows the transfer of the toner to the transfer member.
