Abstract
There is provided a toner block, which is formed by preparing a toner suspension in which toner particles are dispersed in water so that a water amount is 32.5 to 37% by mass; absorbing water contained in the toner suspension by a water absorptive material which absorbs 0.2 ml of water within 3 minutes to prepare an aggregate of the toner particles containing water of not more than 32.3% by mass; and drying the aggregate, and which has a maximum compressive stress of 80000 to 550000 N/m2 upon collapse.
