PURPOSE:To obtain a toner compsn. having high electrostatic charge stability and superior cleaning effect by using a mixture consisting of toner particles and fine particles of acrylic polymer obtd. by a dispersion polymn. in a nonaq. solvent. CONSTITUTION:The toner compsn. is produced by admixing fine particles of acrylic polymer obtd. by a dispersion polymn. in a nonaq. solvent to toner particles. Preferred particle size of the fine particles of the acrylic polymer is 0.05-2, particularly 0.1-1mum. Preferred amt. of the fine particles of the acrylic polymer to be used is generally 0.01-1, particularly, 0.05-0.15pts.wt. based on 100pts.wt. toner. Thus, cleaning effect, electrostatic charge stability, and durability of a toner compsn. are improved, and distinct copied picture are formed for a long time. |
