Abstract
PURPOSE: To enhance the distinctness of developed images and increase resolution while maintaining the advantages of an elastic roller by disposing a turning member forming a developing solution pool region in contact with the elastic roller, in proximity to an electrostatic latent image carrier.
CONSTITUTION: A developing roller 43 consisting of a central axis roller 2, elastic foam 3 and screen 4 makes contact to a drum form photoreceptor 18 past a latent image forming means 37, in the state where it has sufficiently drawn up a developing solution 40, thereby forming the nip part x. The liquid 40 squeezed out from the roller 43 is filled in the convex form space z formed by the roller 42 disposed in proximity to the photoreceptor 18 and the roller 43 as they contact. The latent images on the photoreceptor 18 are first edge-developed by the solution 40 stagnating in this region z and are further developed in the nip part x. Next, at the time when the roller 43 detaches from the photoreceptor 18, it sucks in the excess solution 40 near the photoreceptor 18 and further the solution 40 is exchanged and replenished by the fresh roller 44 which is pressure-contacted thereto by forming the nip part y in the solution 40 in a solution bath 41.
