Abstract
Provided is a resin composition which contains (A) a polyethylene wax satisfying the requirements (i)-(iv) described below and (B) at least one resin selected from the group consisting of thermoplastic resins and thermosetting resins, wherein the mass ratio of (A) to (B) is from 0.1/99.9 to 50/50. This resin composition is useful for providing a toner which can be fixed by means of a relatively-low-temperature heating body and has good offset resistance, and which is suppressed in increase of particle diameters even if the toner is stored for a long period of time. (i) The weight average molecular weight (Mw) is within the range from 400 to 1,500. (ii) The molecular weight distribution (Mw/Mn) is within the range from 1.2 to 2.5. (iii) The penetration as measured at 25° C. is 5 dmm or less. (iv) The melting point (Tm) is within the range from 50° C. to 110° C.
