Abstract
A toner for electrophotography comprising a colorant and a binder resin, wherein the toner further contains an image reinforcing agent, is disclosed. The reinforcing agent is preferably a high melt viscosity resin whose weight average molecular weight is 300 to 3000 and whose melt viscosity .eta. at 140.degree. C. is 10.sup.3 to 10.sup.6 (Pa.multidot.s). A developer for electrophotography containing a carrier and a toner comprising of a colorant and a binder resin, wherein the toner contains an image reinforcing agent, is also disclosed.
