As a result of various studies and examinations aimed at finding silica-based particles that absorb a large amount of ink, do so quickly, and do not substantially cause powder shedding, we have found that a specific particle shape has been found. It has been found that the above object can be achieved by forming an aggregate of ultrafine particles in which gaps between the particles are maintained.
