Abstract

PURPOSE:To make an adjustment unnecessary at the time of installation by fitting in advance a spacer member to a developing device, cutting the spacer member so that a butt face of the front end of a developer carrying body and the spacer member becomes a prescribed value, and thereafter, fitting it to a device body. CONSTITUTION:When a spacer member for controlling an interval of a developer carrier and an electrostatic latent image forming body is fitted to a developing device on which the developer carrier is provided and the developing device is installed in an electrostatic recording device, a butt face of the spacer member is cut basing on the surface of the developer carrier so that the developer carrier and the electrostatic latent image forming body form a prescribed interval and thereafter, the developing device is installed to the electrostatic recording device. The butt face position of the spacer member is determined basing on a position of the developer carrier after the developing device is assembled, therefore, even if an error exists to some extent in dimensions of the developing device member, necessary dimensions are obtained exactly at the time of finish, and an adjustment at the time of installation to the body is unncessary.

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.

In addition, the developing device must be able to be easily removed from the electrostatic recording device main body for maintenance etc., and it must be able to be installed again.
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.

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.

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.
