TONER FOR DEVELOPMENT OF ELECTROSTATIC IMAGES |
| 摘要 |
The object of the present invention is to provide a toner for development of electrostatic images (hereinafter referred to as toner) which, while preventing dust during fixation, secures improved hot offset resistance and is excellent in providing good image quality. The invention relates to the toner that comprises a binder resin, a colorant and a wax, wherein the wax has, while in a state of being contained in the toner, a melting point of from 55° C. to 90° C., and the value Dt of the toner satisfies a specific formula. |

1. A toner for development of electrostatic images comprising a binder resin, a colorant and a wax, wherein:
the wax that is in a state of being contained in the toner for development of electrostatic images has at least one melting point falling within a range of from 55° C. to 90° C., and a dust emission (Dt) from the toner for development of electrostatic images satisfies the following formula (1):
101≦Dt≦195,449/Vp−1,040 (1)[wherein Dt represents a dust emission per minute (CPM) when heating the toner for development of electrostatic images, Vp represents a printing speed (sheets/min) in terms of A4 short side feed in an image forming device, and Vp is 171.2 or less.] |
