Abstract
Latent images on sheet-like carriers are developd by attracting that side of a carrier which faces away from the image to the convex external surface of a first support which constitutes a portion of or an entire hollow drum and is rotatable in at least one direction. A concavo-convex electrode is outwardly adjacent to and spaced apart from the path of movement of the carrier on the first support and can be mounted directly on the first support or on a discrete second support which is coaxial with and can be rotated with as well as relative to the first support. The electrode and the carrier define an arcuate developing chamber of constant width which receives a supply of developing liquid when the one and/or the other support is rotated to place the carrier into register with the electrode or to simultaneously rotate the carrier and the electrode to a position in which the developing liquid can flow downwardly and into the developing chamber. The development of the image on the carrier is terminated by rotating the one and/or the other support in the same direction in which the support or supports are rotated to contact the carrier by the developing agent. This insures that the developing agent contacts each and every portion of the image for the same interval of time.
