A toner container of the present invention includes a cylindrical portion
containing toner used in an electrophotographic type complex machine.
When the cylindrical portion is driven to rotate, the toner gets out via
an outlet thereof. The cylindrical portion of the toner container has an
inner wall provided with a coat layer containing fluorine-containing
silica fine particles, which are obtained by modifying a property of the
surfaces of silica fine particles by using a fluorine-based silane
coupling agent. This coat layer effectively prevents the toner from being
adhered to the inner wall of the toner container.
