PURPOSE:To prevent agglomeration of a toner, by using a toner contg. a one- component type magnetic toner as a main component, and adding a small amt. of ferromagnetic particles. CONSTITUTION:A one-component type magnetic toner T obtd. by adding 50pts. wt. magnetite to a styrene-acrylic resin further contains ferromagnetic particles A made of high-resistivity ferrite by 0.5pt.wt. A per 100pts.wt. of the toner T. The presence of the ferromagnetic particles A strengthens feed of the toner T on a developing sleeve 3, and prevents agglomeration of the toner T. |
