PURPOSE:To obtain the improve title composition which has a less unevenness of development by incorporating a polyethylene oxide adduct or a polypropylene oxide adduct of glycerol in an aqueous solution of alkali silicate. CONSTITUTION:The polyethylene oxide adduct or the polypropylene oxide adduct of glycerol is incorporated in the aqueous solution of alkali-silicate in an amount of 0.001 to 10wt.% based on the alkali-silicate. The used alkali- silicate is exemplified by sodium silicate, potassium silicate, lithium silicate and ammonium silicate, etc., and may be used solely or together with an another alkaline agent. The another alkaline agent is exemplified by sodium hydroxide, potassium hydroxide and lithium hydroxide, etc. Thus, the improved developer composition which has the less unevenness of development and a less foaming is obtd. |
