Abstract
A liquid developing apparatus including a photosensitive element forming an electrostatic latent image thereon, a developing roller for supplying a developer to the photosensitive element, a squeezing roller for squeezing the photosensitive element, and a regulatory roller for preventing the spread of the surplus developer. By employing the liquid developing apparatus, most of the developer on the photosensitive element can be maintained thereon and properly discharged.
Claims11
A liquid developing apparatus comprising:
- a photosensitive element having an electrostatic latent image thereon;
- a developing roller for supplying a developer to the photosensitive element;
- a squeezing roller for squeezing the photosensitive element;
- and
- a regulatory roller located upstream the squeezing roller and opposing to the photosensitive element, the regulatory roller including a pair of annular projections projecting therefrom in a radial direction in vicinity of both ends of the regulatory roller for maintaining the developer on the photosensitive element between the annular projections.
