Background technology
In the past, usually needed the powder toner of used for static latent image developing from tun small lot ground, separately be fills up to other the container.For example, open a kind of like this toner powder placement method in the flat 9-183902 communique of Japanese Patent Publication Laid-Open: described toner powder placement method is the toner powder to be provided with the toner stirring internally be fills up in the toner receiving vessel with container with the toner supply that rotor, bottom are provided with rotovalve, described method comprises: gas is imported in the toner that is in described toner is supplied with container under the stirring, to improve the operation of toner flowing power; Use delivery duct, described toner is delivered to the toner receiving vessel, the toner that is delivered to the toner receiving vessel is compressed, make it densification, carry out the operation of filling; At this moment, above-mentioned delivery duct midway and toner be provided with to circulate between supplying with container and use freeing pipe, gas componant is separated with freeing pipe by this circulation, will be mixed in toner in the above-mentioned divided gas flow, be back to above-mentioned toner once again and supply with and use container with this gas.
Yet the used for static latent image developing toner is the very tiny powder of particle diameter, and its density proportion is little than the powder of other materials such as Tao Ci etc., but its flowing power is poor, and coherency is big.Particularly recently, for complying with the requirement that improves developed image exploring degree, used for static latent image developing toner diameter of particle is towards more and more tiny small particle diameter development.In addition, for responding energy-conservation and instantaneous high-revolving photographic fixing requirement, also exist and use the more tendency of the molten resin of low temperature.But toner powder cohesion performance and the adhesion value of body surface, conjunctiva etc. are become problem.Therefore, for improving the above-mentioned character of toner, avoid its flowing power to reduce and cohesion, in many occasions, must prevent the ultrafine particle of agent etc. in toner particle surface mounting flow property improving agent and coherency, for improving the charged characteristic of toner, mounting charge adjusting agent ultrafine dust.So, from preventing that mounting from considering in the viewpoint of the separation of these ultrafine dusts on toner surface, the charge characteristic that comes off, keeps toner, flowing power and anti-coherency etc., it is unfavorable that the use meeting produces to toner that the rotor of excessive strain or the such device of spiral belt conveyor stir or transmit.
