| 摘要 |
The present invention provides a toner comprising a binding resin, a colorant, and an ester based wax having an iodine value of not more than 25 and a saponification value of 30 to 300 (for example, at least one selected from the group consisting of meadowfoam oil and derivatives thereof and jojoba oil and derivatives thereof) and a method for producing the same. The present invention also provides a toner comprising silica fine powder containing a component having a polydimethyl siloxane skeleton extracted by an organic solvent at a content of not more than 2.5 wt %, and a method for producing the same. This stabilizes the chargeability and flowability of the toner during long period use, and reduces the filming on a photoconductive member or a transfer medium. Moreover, toner that provides good fixability, anti-offset properties, waste toner recycle properties, and transfer efficiency can be obtained with good reproducibility.
