Abstract
PURPOSE: To prevent scattering and fuming of a toner and yet to be easily pulverizable to a proper powder in a developing unit, by agglomerating a toner containing a binder and a colorant into granules of diameter ≥ a specified value.
CONSTITUTION: A binder for which all the known materials are available, and a colorant, such as carbon black are mixed and pulverized, melted and kneaded, then finely pulverized, and the obtained toner of 0.5W70μm particle diameter is formed into agglomerate granules of the minimal granule diameter ≥100μm in a basket type granulator. It is preferable to form it into a cylindrical shape of 0.1W0.8mm diameter. This granular toner is prevented from scatteing and fuming in particulates in its handling, such as feed to a developing unit, and staining the environment, a human body, the machine, etc., but it is easily converted into the initial powder suitable for superior development in use in the apparatus.
