Process for the production of an electrophotographic liquid developer containing gelatin |
| abstract |
A process for producing a liquid developer for developing electrostatic latent images which comprises (1) adding to an aqueous solution of gelatin, the concentration of the gelatin being in the range of approximately 1 to 20 percent by weight, an alcohol in an amount less than that of causing the precipitation of gelatin to provide a solution of gelatin in a water-alcohol mixed solvent, (2) dispersing the solution thus prepared in an organic solvent which is miscible with water but is a non-solvent for gelatin to form a dispersion of fine gelatin particles where the amount of said organic solvent is at least 10 times the amount of the mixed gelatin solution of water and alcohol and recovering the fine gelatin particles from the dispersion, and (3) dispersing the fine gelatin particles thus recovered in a carrier having an electric resistance of higher than 101010 Omega cm. |
