Positive chargeable magnetic toner composition |
abstract |
The present invention relates to a magnetic mono-component toner composition with positive charge comprising i) a magnetic toner particle containing a charge control agent with positive charge; ii) a hydrophobic silica with negative charge; iii) a fluorinated organic fine powder; and iv) a metal oxide fine powder containing 20 to 80 wt % of tin oxide. The toner has an advantageous in the extended life of the drum, reduction of the background contamination, and improvement of long-term reliability, and thus can be used effectively for image forming apparatus. |
