Abstract
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.
