シール部材が設けられる。2. Description of the Related Art Generally, in an image forming apparatus such as a copying machine or a printer, the surface of an electrostatic latent image carrier is charged by a charging device, and an electrostatic latent image is formed by imagewise exposing the charged area. The latent image is visualized by a developing device, the obtained toner image is transferred to a transfer material by a transfer device, and the transferred toner image is fixed on the transfer material. After transferring the toner image to the transfer material, the residual developer remaining on the surface of the electrostatic latent image carrier is removed by a cleaner,
The residual charge is erased by the eraser. Further, in order to prevent the developer from leaking, the developing device or the like is provided with an appropriate developer seal member.

写装置が注目されている。A corona charging device is widely used for the charging device because it can perform stable charging. However, the charging device is a type of ozone that adversely affects the human body and deteriorates the surface of the electrostatic latent image bearing member. Since a large amount of ozone is generated, a brush charging device that produces a significantly small amount of ozone is drawing attention. Although a corona transfer charger is widely used in the transfer device, a brush transfer device is also drawing attention because of the generation of ozone.

法が採られている。As described above, the image forming apparatus requires a charging brush and a transfer brush. Further, although an erase lamp is generally used as the eraser, a charge eliminating brush may be used, and a brush may be used as a seal member in a developing device or the like. These brushes can be obtained by various manufacturing methods. As an example, looking at the manufacturing method of a charging brush, for example, as disclosed in JP-A-61-47970, a brush bristle thread is woven into a base cloth in a wavy shape. , A method of forming a large number of bristles having a looped end and winding the base cloth around a roll core to produce it, collecting a plurality of brush bristle threads into a bundle, and using the bundle as a base cloth A method of weaving into a V-shape, a W-shape, etc., and then cutting the tip of the thread to a certain height to form brush bristles, and fixing the base cloth to a back plate or the like is adopted.

画像ノイズが発生する。Of these, the charging brush whose base cloth is fixed to a back plate or the like is usually arranged at a fixed position with respect to the surface of the moving electrostatic latent image carrier, and the bristles of the brush come into contact with the surface. In this case, when the electrostatic latent image carrier is formed in a cylindrical shape or a cylindrical shape like a photoconductor drum, it is difficult for all the brush bristles to uniformly contact the surface of the photoconductor drum. A fixed charging brush often causes streak-shaped image noise.

号公報参照）。Therefore, in order to solve this problem, the brush bristles are supported on the curved surface of the back plate having a curvature substantially matching the curvature of the surface of the photosensitive drum, whereby the brush bristle tip gathering surface is made to correspond to the curvature of the surface of the photosensitive drum. A method has also been proposed in which the brush bristles are made to substantially coincide with each other and the bristles of each brush are brought into uniform contact with the surface of the photoconductor drum (Shokai 61-81666).
(See the official gazette).

ればならない。However, it is very difficult to machine the back bristle supporting surface for supporting the brush bristles or the brush bristle supporting surface of the base in such a manner as to have a curvature substantially matching the curvature of the surface of the photosensitive drum. It is time consuming and expensive. Further, not only the charging brush, but also the transfer brush, the charge eliminating brush, the developer seal brush,
Even if it is desired to finish the shape of the brush bristle tip gathering surface according to the surface shape of the mating member with which the brush comes into contact, it is currently under actual conditions.
The manufacturing method of the charging brush disclosed in No. 6 must be the same.
