The invention discloses a novel developer rinsing and pressing plate, comprising a developing device disposed in a developer body. The developing device comprises an orifice plate horizontally disposed in the developer body. The two ends of the orifice plate are fixedly connected to the inner wall of the developer body. The upper end surface of the orifice plate is fixedly connected with two symmetric vertical plates. A pressing mechanism, a rinsing mechanism, and a brushing mechanism are successively arranged between the two vertical plates in the horizontal feeding direction. The pressing mechanism comprises a fixed pressure roller mounted on the orifice plate. A movable pressure roller mechanism corresponding to the fixed pressure roller is disposed over the fixed pressure roller. The sidewalls of the two vertical plates are provided with horizontal stopping mechanisms. By using a linkage mechanism, the novel developer rinsing and pressing plate rotates a nozzle pipe forward and backward repeatedly when brushing the surface by a brush cylinder, thereby swinging the rinsing water flow and achieving a better rinsing effect.
