摘要： Upper and lower guides are curved in the direction of the path of movement of the copy material to be developed and extend transversely of such path for a distance greater than the width of the copy material. Opposed walls are connected with the ends of these guides to define a confined arcuate space with an inlet slot and an outlet slot. A liquid developer distribution outlet opens into such arcuate space adjacent to and inwardly of the inlet slot for distributing a flow of developer fluid in a pattern extending transversely of said path for a distance substantially the same as the width of the copy material. The liquid developer is forced through said outlet under pressure resulting in a turbulent flow of the developer liquid throughout the arcuate space thereby causing a substantial quantity of fresh, active, charged toner particles to come into contact with the latent electrostatic image on the copy material.
