TONER |
摘要 |
The present invention is to provide a toner that has a total volatile organic component content (TVOC content) reduced to a low level, is less likely to cause fog even when used in either a low-temperature and low-humidity environment or a high-temperature and high-humidity environment, does not cause filming even in continuous printing, and is excellent in printing durability. Disclosed is a toner comprising a binder resin, a wax, a charge control resin and a colorant, wherein, as a result of gas chromatography analysis of a supernatant obtained by dissolving the charge control resin in a first organic solvent to prepare a charge control resin solution and then adding a second organic solvent to the charge control resin solution to precipitate a polymer component and to obtain the supernatant, a first total amount of components detected in a range of a peak detecting time of hydrocarbons having 5 to 9 carbons is 500 ppm or less in terms of styrene; a second total amount of components detected in a range of a peak detecting time of hydrocarbons having 10 to 18 carbons is 5,000 ppm or less in terms of styrene; and an amount of a component corresponding to a maximum peak of peaks of hydrocarbons having 10 to 18 carbons is 3,000 ppm or less in terms of styrene. |

1. A toner comprising a binder resin, a wax, a charge control resin and a colorant,
wherein, the charge control resin is obtained by polymerization using an azo compound as a polymerization initiator and drying treatment conducted for 10 minutes to 24 hours under conditions of a drying temperature of 35 to 80° C. and a pressure of 0.5 to 20 kPa, wherein, as a result of gas chromatography analysis of a supernatant obtained by dissolving the charge control resin in a first organic solvent to prepare a charge control resin solution and then adding a second organic solvent to the charge control resin solution to precipitate a polymer component and to obtain the supernatant, a first total amount of components detected in a range of a peak detecting time of hydrocarbons having 5 to 9 carbons is 500 ppm or less in terms of styrene; a second total amount of components detected in a range of a peak detecting time of hydrocarbons having 10 to 18 carbons is 5,000 ppm or less in terms of styrene; and an amount of a component corresponding to a maximum peak of peaks of hydrocarbons having 10 to 18 carbons is 3,000 ppm or less in terms of styrene. |
