A developer apparatus is provided for developing exposed diazotype copy sheets comprising an applicator roller, means for supplying liquid developer to the applicator roller, a metering blade for wiping excessive liquid from the applicator roller and a pressure blade for pressing a copy sheet against the surface of the applicator roller to transfer liquid from the applicator roller to the copy sheet to develop an image thereon. The metering and pressure blades are arranged for sliding movement between an inoperative position ineffective to develop the copy sheet and an operative position in pressure engagement with the applicator roller for developing the copy sheet. Cam and linkage control means is provided for sequentially moving the blades between the inoperative and operative positions under control of a manually operable actuating means.
