Abstract
A particle surface-modifying method has the steps of suspending particles in a liquid containing a modifier so as to prepare a suspension, and heating the suspension while it is being transported so that the surface of the particles is modified by the modifier. This method makes it possible to provide surface-modified particles having a comparatively small particle size at low costs for a short time by using simple operations, without causing the particles to be charged.
