Patent ID: 7113730

Claim:
An apparatus to prevent developer wraparound in a wet electrophotographic printer, comprising: a developer storing space to store a liquid developer: a photosensitive body to form a latent image: a developer transfer body rotated to face the photosensitive body, to transfer the developer from the developer storing space to the photosensitive body to form a visible image according to the latent image, the developer transfer body comprising a first portion having a first diameter which is substantially constant, and a second portion extended beyond at least one of both ends of the first portion along a longitudinal axis of the developer transfer body and having a varied diameter comprising a plurality of second diameter portions smaller than the first diameter: and at least one developing density restricting roller to restrict at least one of an amount and a density of toner particles of the liquid developer supplied per unit area of the developer transfer body, the at least one developing density restricting roller being constructed to have a shape conforming to the developer transfer body, wherein the developer transfer body is formed in a roller shape, and at least a portion of the second portion is tapered at a predetermined angle toward a corresponding end of the developer transfer body to prevent the at least portion of the second portion from being in contact with the photosensitive body, and wherein the developing density restricting roller comprises at least one end portion formed to have a shape conforming to the second portion of the developer transfer body to make a compressive contact therebetween.
