The latent image is visualized with toner, and the toner image is transferred to a recording material to perform image recording. In such an apparatus, the toner must be replenished each time it is used up, but this toner replenishment work is not only troublesome, but it may be contaminated. In addition, maintenance of each member can be performed only by a specialized service person, which often causes inconvenience to the user.

It is provided with at least one process means. Here, examples of the process means include a charging means for charging the surface of the image carrier, a developing means for forming a toner image on the image carrier, and a cleaning means for cleaning toner remaining on the surface of the image carrier. As shown in FIG. 7, the process cartridge of the present embodiment has a charging unit 8, an exposing unit 9, and an exposing unit 9 around an electrophotographic photosensitive drum 7, which is an image carrier.
A developing means 10 for developing with toner and a cleaning means 11 are arranged, and these are covered with a housing composed of a toner frame 12, a developing frame 13 and a cleaning frame 14 to be integrated with each other, and detachably mountable to the apparatus main body 15. doing.

A toner feeding member 10b that rotates in the direction is provided. Further, the toner sent out is rotated on a developing sleeve 10d having a magnet 10c therein to form a thin toner layer on the surface thereof. When the toner layer is formed on the developing sleeve 10d, the friction between the toner and the developing sleeve 10d causes the photoconductor drum 7 to rub.
It has sufficient triboelectric charge to develop the above electrostatic latent image. A developing blade 10e is attached in contact with the surface of the developing sleeve 10d to regulate the layer thickness of the toner.

口部内径より大きく設定し、圧入させて挿入する事によ
りシール性を十分なものとしていた。The cap 30 for sealing the opening of the toner frame is made of a soft elastic material (such as low density polyethylene), and the diameters of the protrusions 30a, 30b, 30c provided on the cap 30 are set. By setting the inner diameter of the toner frame to be larger than the inner diameter of the toner frame and inserting the toner frame by press-fitting, the sealing property is sufficient.

実に防止するためである。The reason why the cap 30 is provided with three protrusions (a plurality of protrusions) is that the material of the cap 30 is low-density polyethylene, and the material of the toner frame is polyethylene resin (ABS: acrylonitrile butadiene styrene). Since it is configured, due to the difference in shrinkage rate due to temperature change,
This is to reliably prevent the sealing property of the cap 30 from the toner frame body from decreasing.

コストダウンが可能となる。By making the material of the lid 40 the same as that of the container, it is possible to prevent the instability of the sealing property due to temperature change without occupying a space. Conventionally, the sealing is achieved by press-fitting the cap, so that the entire sealing portion is stable. Although a large number of circles are used for sealing, the present invention has a round shape, but since various shapes other than the round shape can be accommodated, the space can be effectively used. As a result, the area of the toner filling port can be increased, so that the toner can be efficiently filled in the toner frame, and the time required for the toner filling can be shortened to reduce the cost.
