In certain magnetic systems (as well as other reprographic systems), it is desirable to be able to selectively turn on and off a development subsystem for part of a process cycle. Referring to the accompanying figure, for example, it is desirable to have the developer 1 develop the latent image on the receptor or drum 2 every other revolution of that receptor. Thus, during a first full rotation of the image receptor 2 an image is formed on that receptor by an imaging substation (not shown). On the next rotation of the receptor 2, the developer 1 forms a visible image by bringing toner or developer material 3 into contact with the image on the receptor 2. OR the next rotation of the receptor, the next image is formed and the developer 1 is rendered inoperative so that no development takes place.
