現像を行っている。In an electrostatic recording device using dry development, an electrostatic RU image formed on an electrostatic image forming body such as a photocardiographic light body in so-called electrostatic photography or a dielectric body in a multi-stylus method is used. On the other hand, development is carried out by bringing the developer supported on the turned-off developer carrier provided in the developing device into contact with each other to make the toner stick to the toner.

ている。Generally speaking, a so-called magnet roller is used as a developer carrier, which has a plurality of loosely fixed rod-shaped magnets mounted on a rotatable non-magnetic sleeve. FIG. 1 is a schematic diagram of a developing device using a magnetic roller, where N1 is a main magnet, the other N or S is an auxiliary magnet, and 1
The sleeve rotates in the direction of the arrow. 2 is a 44 agent containing a magnetic substance that is attracted to the magnet and adheres to the surface of the sleeve 10 (thus forming a so-called magnetic brush, which moves as the sleeve rotates. First, the sleeve 1 comes into contact with the BI electrostatic image formed on the drum 4 near point A where it approaches the electrostatic latent forming member drum 4, and development is performed. This is the housing of the developing device.In addition, inside the developing device there is a developer stirring plate,
Although a toner conveying screw and the like are provided, they are omitted from the drawing.
その最適[[Jは現像剤の性質、種類等によって異るが
、いづれの場合にも高品質の画像を得るためには極めて
関い精度か要求される。The optimum [[J] varies depending on the properties, type, etc. of the developer, but in any case, extremely high precision is required in order to obtain a high quality image.

a must always be reproduced with high precision. For this reason, a method has been adopted in which a spacer member is attached to the developing device, and the position of the developing device is determined by abutting against part of a stopper provided on a side plate that holds the electrostatic latent image forming drum, thereby keeping the distance d constant. Ta. FIG. 2 shows an example of how the developing device is attached by the above method. 21 is a developing device, 22 is a sleeve, 23 is a spacer member attached to both sides of the developing device, 24 is a side plate holding an electrostatic latent image forming drum 26, and 25 is a stopper portion. Next, the imager is mounted from the direction of the arrow, and is fixed at the position where the spacer member 23 hits the stopper part 25. Other earthworks for the developing device and members for holding and fixing the developing device in the left and right directions are provided (71) and are omitted from the drawing.

ことができる。In the above structure, the distance from the abutment surface of the spacer part to the front end of the sleeve and h from the AiJ end of the stopper part are
't If the distance between the latent image forming drum and the front end of the side opposite to the sleeve is prepared with sufficient accuracy, when the developing device is installed, the distance d between the sleeve surface and the electrostatic latent image forming drum should be adjusted to the required distance. It is easy to maintain the accuracy within the range, and even when the developing unit is repeatedly attached and detached, a satisfactory reproduction accuracy can be obtained.

の量産に適するものではなく、現像器の互換性について
も不完全であった。However, in a developing device that is made up of many parts that are assembled using many materials such as glass stick, even if the dimensional accuracy of each part is improved, the distance between the abutment surface of the spacer member and the front end of the sleeve after assembly cannot be maintained at a predetermined accuracy. It is difficult to finish the inner part, so in the past, the developing device was attached to the main body each time after assembly, the distance between the electrostatic latent image forming drum and the magnetic roller sleeve was measured with a thickness gouge, etc. The above problem was fixed by moving the screws or pasting a thin metal piece prepared in advance on the abutment part, but these operations required a lot of time and the skill of the miller, making it difficult to mass-produce the equipment. It was not suitable, and the compatibility of developing devices was also incomplete.

た突当面が形成される。The method and tools for cutting the abutting surface are not particularly limited, and any tool may be used as long as it can cut with high precision based on the front end of the developer carrier. , an example of a preferred processing machine for this purpose is shown in No. 4N. The processing machine has a stopper 41 that determines the position of the developing device to be processed, a cutting tool 42, and a drive 1 that drives the cutting tool 42.
- a motor 43 for raising and lowering the cutting tool 42 and the drive motor 43, a unit 44 for raising and lowering the cutting tool 42 and the drive motor 43, a circle 1 motor 45 for raising and lowering the 44, and restraints 46 and 47 for fixing the developing device to be processed from above and from the rear. Processed first developing device 48
A magnetic roller 49, which is a developer carrier installed in the container, is placed against the stopper 41 and fixed onto the processing machine using the diagonal inserts 46 and 47. The cutting tool 42 is rotated and lowered to cut the spacer part 50. Stopper 4
If the distance between the surface 10 and the cutting surface of the cutting tool 42 is adjusted to a certain value tXd in advance, an abutment surface with a predetermined distance from the front end of the magnet roller 49 will be formed on the developing spacer member 51. be done.
