Patent ID: 6873351

Claim:
A system for sharing characteristics of photosensitive mediums, comprising: a plurality of image forming apparatus each having a loader for being loaded with photosensitive mediums, attribute information readers for reading attribute information of photosensitive mediums when the photosensitive mediums are loaded into said loader, an image forming assembly for exposing photosensitive mediums to image light to form a latent image thereon and developing the latent image into a visible image under image forming conditions depending on density characteristics of said photosensitive mediums, and a density measuring unit for measuring density characteristics of images formed on said photosensitive mediums; and a characteristics storage and retrieval apparatus connected to said plurality of image forming apparatus by a local area network, for storing the density characteristics of said photosensitive mediums which are measured by the density measuring units of said image forming apparatus in association with said attribute information; wherein said image forming apparatus share the density characteristics of said photosensitive mediums which are stored in said characteristics storage and retrieval apparatus.
