Latest Patents
Nakamura's latest patents include advancements in silicone oil-treated silica particles and toner for electrophotography. The first patent describes a silicone oil-treated silica particle that consists of a silica particle body and silicone oil. This silica particle body has a BET specific surface area ranging from 70 m/g to 120 m/g and is treated with silicone oil. The amount of free silicone oil released from the surface of the silica particle body is between 2.0 mass % to 5.0 mass % relative to the silica particle body. Additionally, a surface-treated styrene acrylic resin particle, which incorporates 2 parts by mass of the silicone oil-treated silica particle into 100 parts by mass of a styrene acrylic resin particle with a median particle size of 5 µm to 8 µm, exhibits a degree of agglomeration of 18% or less.
