摘要： A toner for static charge image development that has satisfactorily high charging capacity, that even after output of several ten thousand imaged sheets, minimizes the amount of toner spent on carrier, etc., can sustain high charging capability and fluidity and can reduce ground surface stain (fogging), and that excels in low temperature fixation and hot offset properties, exhibiting large fixing temperature width. There are further provided, utilizing the toner, a developer, image forming apparatus and method of forming image. In particular, there is provided a toner for static charge image development, comprising at least a colorant and a resin, characterized in that at least a fluorinated compound is present on its surface, the atomicity ratio (F/C) of fluorine atoms to carbon atoms on toner particle surface being in the range of 0.010 to 0.054.
