Description of the Related Art Dry developing methods used in electrophotography and electrostatic recording include a method using a two-component developer composed of toner and carrier and a method using a one-component developer containing no carrier. is there. The former method can obtain a relatively stable and good image, but it is difficult to obtain a constant quality for a long period of time because carrier deterioration and variation in the mixing ratio of toner and carrier are likely to occur. Moreover, there is a problem in maintenance and compactness of the device. Therefore,
The latter method using a one-component developer, which does not have such drawbacks, has been receiving attention. By the way, in this system, there is usually a means for carrying toner (developer) by at least one toner carrying member and for visualizing the electrostatic latent image formed on the latent image carrier by the carried toner. However, at that time, it is said that the layer thickness of the toner conveyed on the surface of the toner conveying member must be made as thin as possible. This is true even when using a two-component developer whose carrier has a very small diameter. In particular, when a one-component developer is used and its toner has high electric resistance, When used,
Since this toner needs to be charged by the developing device, the toner layer thickness must be made extremely thin. This is because if the layer is thick, only the surface of the toner layer is charged, and it becomes difficult to uniformly charge the entire toner layer.

解決されていない。In response to such a request, various methods have been proposed as means for controlling the toner layer thickness on the toner carrying member (toner layer thickness controlling means). As a typical example, a doctor blade is used, and this blade is used for carrying toner. The toner layer thickness is controlled by placing the toner on the surface of the toner conveying member and pressing the conveyed toner on the surface of the toner conveying member with a pressing member (doctor blade). However, with this alone, it is difficult to uniformly convey the toner to the toner conveying member. Therefore, there has been proposed a developing device that is rotatably supported while being in contact with the toner conveying member and has a toner supply unit that supplies the toner onto the toner conveying member.
When the development is continuously performed, the ability to supply the toner to the toner conveying member is lowered, and the image density is lowered.
There are two causes for this: deterioration of the toner replenishment property from the toner hopper to the toner supply member, and further deterioration of the toner replenishment property from the toner supply member to the toner transport member. Attempts have been made to add a surface-active substance and a fluidity modifier to the toner in order to solve the above-mentioned drawbacks, but they have not been sufficiently solved yet.

ては、以下のようなものがある。Means for Solving the Problems The inventors of the present invention have made extensive studies and found that when a positively chargeable toner is used in the developing device, at least the surface of the toner supply member is coated with a specific fluorine compound. The inventors have found that the problem can be solved by using a developing device in which a bias of 0 to 500 V positive potential is applied to the toner supply member from the toner transport member, and have reached the present invention. That is, the present invention is a developing device including at least a toner transport member and a toner layer thickness regulating member, and a toner supply member that is rotatably supported while being in contact with the toner transport member and that supplies toner onto the transport member. In the apparatus, at least the surface of the toner supply member is coated with at least one aromatic fluorine compound selected from the group of compounds represented by the general formulas [Chem. The positive charging toner developing device is characterized in that a bias of 0 to 500 V positive potential is applied to the toner conveying member. Although the cause of the solution is not clear, by coating the toner supply member with the above compound, the positively chargeable toner in the toner tank of the developing section is smoothly replenished to the toner supply member, and the toner supply member is 0 to 50 from the toner transport member
By applying a bias of 0 V positive potential, the toner on the toner supply member is smoothly accumulated on the toner conveying member without accumulating, the toner flow in the developing device becomes smooth, and the toner on the toner conveying member is smoothed. It is considered that this is because the toner layer thickness can always be kept uniform. Examples of the aromatic fluorine compound represented by the above general formula used in the present invention are as follows.

A sponge-like material, a fur brush-like material, and the like are conceivable, but the material is not limited to these. Further, as a method for coating the surface of the toner supply member with the substance of the present invention, the toner supply member may be immersed, sprayed or brushed in a coating solution obtained by dissolving or dispersing it in a solvent or a dispersion medium as required. Can be applied. What is important in the present invention is that the toner supply member is surface-treated with a substance having a negative charging property with respect to the toner. In the case of a substance having no negative charging property, the toner is supplied by the toner supply member. The toner is not sufficiently negatively charged negatively, the toner is not replenished to the supply member sufficiently, and the toner is not sufficiently supplied to the toner conveying member, so that a uniformly thin toner layer that is uniformly charged cannot be obtained. More importantly, as a coating material for the surface of the toner supply member, it should be stable and positively charged to the toner without being deteriorated by heat or with time even after long-term use. is there. Further, by applying a bias of 0 to +500 V to the toner supplying member from the toner conveying member, the toner is rapidly replenished from the toner supplying member onto the toner conveying member. If the applied bias is a negative potential, the transfer of the toner onto the conveying member becomes insufficient, and if it is more than + 500V, the toner filming on the toner conveying member occurs, and the background fog or the like is generated by running. Occurs on. As the toner used in the developing device of the present invention, substantially all of the conventionally known toners used as positively charging toner for electrostatic charge development can be effectively used. That is, both non-magnetic and magnetic toners are used. Further, the toner is colored particles in which a colorant is dispersed in a binder resin, and
A dye / pigment or a so-called charge control agent may be contained in order to impart an electric charge.

板表面にコートしたものは、負極性に帯電した。Example 48 As Example 41, except that the exemplified compound [Chemical Formula 6]-(12) was used as a coating material for the toner supply member 4 instead of the exemplary compound [Chemical Formula 6]-(1) of Example 41. Using the same device and toner, a bias of -100 V was applied to the toner feeding member of -250 V to the toner supplying member, development was performed in the same manner as in Example 41, and an image was formed. A clear image was obtained. Subsequently, when 50,000 sheets were continuously copied, a clear image similar to the initial one was obtained. Further, the specific charge amount (Q / M) of the toner on the toner transport member is initially +11.7.
(Μc / g) was sufficient, and Q / M after continuous copying of 50,000 sheets was +10.8 (μc / g), which was almost the same as the initial value. Furthermore, even under high temperature and high humidity of 35 ° C. and 90% RH and in low temperature and low humidity environment of 10 ° C. and 15% RH, image quality equivalent to that at normal temperature and normal humidity was obtained. The triboelectrification property between the coating liquid coated on the surface of a metal plate and the toner was applied to the toner suction specific charge amount measuring device as described above, and its charging polarity was examined. Those coated on the plate surface were negatively charged.
