Abstract
PURPOSE: To obtain good fixing with good efficiency without using offset-preventing liquid for heat-fixing of toner by containing coloring agents, vinyl-toluene-base resin and low-molecular-weight polypropylene.
CONSTITUTION: The toner contained with 1W20pts.wt., based on 100pts.wt. of the resin components in the toner, of vinyl toluene alone or its copolymer with other monomer of mean molecular weight 3000 or more and vinyl toluene content 30wt% or more and low molecular weight polypropylene of mean molecular weights about 1000W45000 and softening points 100W180°C together with coloring agents such as carbon black is produced. This toner is mixed with carrier to prepare the developer. By using this and a copying machine equipped with a working fixing roller of Teflon or the like, the occurrence of the contamination of the fixing roller and offset phenomenon may be obtained and distinct images obtained. In addition, the toner is stable without change in its long-term friction chargeability.
