PURPOSE:To obtain a toner superior in offset resistance and fixability and capable of forming a high-quality image by using a binder resin made of a polyester resin, and a releasing agent made of low mol.wt. PP or PE. CONSTITUTION:The present toner contains a colorant, at least a releasing agent made of low mol.wt. PP or PE, and a binder resin of a polyester resin made from a diol component and a bivalent or multivalent carboxylic acid or its deriv. component, and it is preferable for the soluble component of said polyester to have a weight average mol.wt. of 5,000-100,000, and a number average mol.wt. of 5,000-20,000, and a mol.wt. distribution of 5-20. |
