ABSTRACT:
There are provided: a method for producing a toner containing to granulate a toner and to subjecting the granulated toner to at least washing with an alkali washing solution, in which the total organic carbon amount extractable from the alkali-washed toner is 200 ppm/g or less; a toner comprising polyester in which the total organic carbon amount extractable from the toner is 200 ppm/g or less, under the condition that the toner is subjected to washing with the alkali washing solution before extracting; and an image-forming method using such a toner.
