摘要：
A toner for developing a latent electrostatic image to a visible toner image, which is suitable for use in an image formation method in which a toner recycle system is adopted, is proposed. The toner is such a toner that a tetrahydro-furan-soluble component contained therein exhibits a sub-peak within a weight-average molecular weight range of 100,000 to 10,000,000 in a molecular weight distribution measured by gel permeation chromatography, and the toner has a water content of 5000 ppm or less when the toner has been allowed to stand at 30° C., 60%RH for 24 hours. An image formation method using this toner is also proposed.
