いるが、現像剤補給器は記録装置本体に組付けている。An electrostatic recording device forms an electrostatic latent image on the surface of an image carrier having a surface layer such as a photoconductive photoreceptor or dielectric, and supplies a developer to the surface of the image carrier using a developing device to form the electrostatic latent image. The developed image is developed and recorded by transferring and fixing the developed image directly onto the surface of the image carrier or onto recording paper, etc., and the developing device is equipped with a developer replenisher to replenish the developer that is consumed during development. is attached. In many conventional electrostatic recording devices, the developer can be detachably attached to the main body of the recording device so that maintenance and inspection can be easily performed. It is being assembled.

電記録装置も知られている。However, in such an electrostatic recording device, 1. When the developing device is removed, there is a problem in that the developer spills from the connection part with the developer replenisher, causing stains inside the device. Therefore, for a developing device that uses a so-called component developer that does not contain a carrier and is mainly composed of magnetic toner, the developing device and the developer replenisher are formed into an integrated developing unit, and the developing unit is removably attached to the recording device. Electrostatic recording devices that can be attached to a main body are also known.

ましく用いられる。On the other hand, recently there has been a demand for electrostatic recording devices that can produce recorded images in various colors. The most suitable method for this purpose is an electrostatic recording device with replaceable development units, which uses developers of different colors for each development unit and allows you to easily obtain recorded images of different colors by replacing the development units. There is. For electrostatic recording devices that can obtain recorded images of different colors, it is necessary for the toner particles of the -component developer to contain a black or brown magnetic material, so that it is possible to obtain recorded images of clear colors. Therefore, a two-component developer consisting of toner particles and magnetic carrier particles, which does not need to contain such a magnetic material, is preferably used.
以上のように、現像ユニット交換可能の静電記録装置は
次第に重要性を増しつつあるのが現状である。As described above, the current situation is that electrostatic recording devices with replaceable developing units are becoming increasingly important.

Rotate clockwise (K) to release the presser bar 6 from the engaging position, then flip up and rotate the presser bar 6 in the counterclockwise direction indicated by the arrow to release the presser on the developing unit 2.
All that is left to do is to lift the developing unit 2 squarely. Then, when the developing unit 2 is lifted up and taken out, the door member 2
The push by the actuating portion 9 provided on the copying machine main body against the driven lever 2fK of e is released, and the driven lever 2f is moved by the spring 2g.
The door rotates counterclockwise due to the bias of the door (Ili12).

から上方に回動退避せしめられる。Therefore, since the door member 2e naturally closes the opening when taking out the developer, the developer is prevented from falling from the opening. Attaching the developing unit 2 is performed by the reverse operation of taking it out. In other words, the presser bar 6
While flipping up the developing unit 2, place it on its fulcrum shaft 2.
1 falls into the shaft seat 10 on the side of the main body of the copying machine, so that its bottom surface contacts the support bar 11 provided on the main body of the copying machine, and then the locking member 7 is pressed against the bias of the spring 8 to lock the clock. This is done by rotating the presser bar 6 in the direction to bring the presser bar 6 to a position where it presses the upper surface of the developing unit 2, and locking the presser bar 6 with the locking member 7. When the developing unit 2 is dropped in, the actuating section 9 of the copying machine main body acts on the driven lever 2fK of the door member 2e, and the door member 2e is rotated upward from the opening.

る。6 and 7 show an example in which the electrostatic recording device is one in which the developing unit 2 is taken in and out in the direction of the thick arrow parallel to the axis of the photoreceptor drum 3. This developing unit 2 has a door member 2e that covers the frontage, and a lever frame 2 that is integrated with the member 2e.
The handle 2) is fed into the recording device on the rail 12 of the recording device main body in a substantially vertical state, and when it hits the handle 2, the protrusion on the lever frame 2 holds the recording device main body. By rotating the door member 2e clockwise until it is completely engaged with the groove 13, the door member 2e is rotated and retracted, and the lever frame 2k of the developing unit 2 is then moved into the engagement groove 13.
The developing sleeve 2a is moved to a predetermined position in the groove where it comes into contact with the driven gauge roller 14 on the recording apparatus main body side due to the reaction from the developing sleeve 2a, and is mounted in the recording apparatus. It is something that This developing unit 2
The recording apparatus cannot be pulled out from the recording apparatus main body unless the handle 2 is rotated counterclockwise to remove the protrusion on the lever frame 2 from the retaining groove 13 of the recording apparatus main body. When the handle 21 is rotated counterclockwise, the lever frame 2k and the door member 2e are also rotated counterclockwise, the door member 2e comes into contact with the protective stay 15, and the developing unit 2 is moved against the protective stay. 15 and retreated to the right, the lever frame 2k hits the restriction bin 2m provided on the side plate of the developing unit 2, and the door member 2e completely covers the opening and stops rotating. Then, by pulling the handle 2 in the axial direction, the developing unit 2 is pulled out from the recording apparatus main body. The spring 2g shown in FIGS. 6 to 8 is a biasing spring for stably maintaining the door member 2e in the opening position and the retracted position, respectively. It also provides the effect of facilitating the operation of moving in the direction perpendicular to the axis of No. 3.

Since the developing unit is provided with a door member K to cover the opening facing the image carrier surface of the developing unit, it prevents the developer from spilling when replacing the developing unit, and also prevents the developing sleeve from being damaged. Since this also prevents this, it is suitably used for recording multicolor images by changing the colors. The electrostatic recording device of the present invention does not use a two-component developer, but may use a -component developer, and the image carrier may be in the form of a belt. .
