が免れなハ欠点を有していた。Conventionally, there have been known copying machines, laser beam printers, LC printers, and other image forming apparatuses that use electrostatic latent materials formed on electrophotographic sensors through a charging and exposure process. What are the process elements of these painter forming devices, such as the ribbon, photoreceptor drum, charger, current unit, cleaning device, etc.? By purchasing an integrated unit (hereinafter referred to as a process unit) and making the entire process unit a consumable item that can be replaced, the overall size of the equipment can be reduced, and the user can avoid maintenance that requires specialized knowledge. A released image forming apparatus has been proposed and is currently being viewed. (For example, Japanese Patent Application Laid-open No. 51-2433.) Such a process unit is designed to prevent copying due to the fact that the rotation axis of the photoreceptor drum is oriented in the direction of gravity when the user replaces it or transports it. , printing defects and toner leakage,
In order to prevent scattering, one handle member is formed so that the rotation axis of the photoreceptor drum becomes a water droplet during handling. Generally, the process unit h having the handle member is roughly divided into 2mK based on the function of the handle member. In one type, the handle for attaching and detaching the process unit and the handle for transporting the process unit are manufactured separately, and in the other type, the handle for attaching and detaching the process unit and the handle for transporting the process unit are the same. These two types of process units have the following features: The process unit of the former ia must be handled with separate handles when it is attached, detached, and transported, making it complicated to handle. In addition, in many of the process units having such a structure, the orientation in which the process unit is energized in the operating state inside the image forming apparatus and the orientation during transportation are such that the rotational axis of the photoreceptor is approximately parallel to the axis of rotation of the photoreceptor. Due to the 90' rotation, toner movement occurs within the developing device and cleaning device, and there is an unavoidable risk of toner leaking out of the process unit and partial deviation.On the other hand, the process unit of the latter structure is for single removable use. Since the handle for transportation is the same, it is easy to handle and operate; It had the disadvantage that there was an unavoidable risk of leakage.

ト8を構成し。Figure 1 schematically shows the main parts of an image forming apparatus using a process unit according to the present invention.
One image, which is an image carrier in which a photoreceptor drum is made of a photovoltaic material such as OPC, is a charger when the image carrier rotatably supported on the main body of the forming apparatus is rotated in the direction indicated by the arrow. 2 uniformly charges the drum surface. This charged portion is exposed to light by the optical signal generator 3, and an electrostatic latent image is formed on the drum surface. Is this electrostatic latent image @ki brush? Developing device 4 to form? As it passes, it is visualized by toner. The toner particles formed in this way are transferred from a transfer paper stacker (not shown) onto a transfer paper (not shown) fed to a transfer stand in synchronization with the toner transfer from the drum 5 (not shown). . After the transfer, the transfer paper is separated from the main photosensitive drum 1'', fed into the fixing device 10, and discharged to a paper discharge tray (not shown). This is an indication. Approximately 30 to 40 q6 of untransferred toner remains on the surface of the photosensitive drum after the transfer has been completed as described above, and the remaining toner is removed by a cleaning device 6. After cleaning, the drum section is neutralized to a certain level by the static elimination rung 7 and prepared for the next image forming process.In the single image forming equipment, the photosensitive main drum 1, the charger 2, and the cleaning cover are among the process elements. 6 is integrated to form a process unit 8.

手14を握り行なわれる。The movable body 11 is configured as a whole. The movable body 11 is supported by a support shaft 12 on a stationary body 13 of the planar forming device. When attaching and detaching the process unit 8, the movable body 11 is rotated in the direction of arrow C, and the process unit 8, which is guided and supported by a guide member (not shown) fixed to the stationary body 13, is attached and detached in the direction of the arrow. The first attachment/detachment operation is performed by grasping the first handle 14.

っている。The handle 14 is a member that is integrally formed with the process unit housing, protrudes from the housing, and extends in the direction of the rotational axis of the photosensitive drum 1 at a position facing the anti-reckoning device 6 on the photosensitive drum 1. It is made up of. The handle 14 is formed in an upright position so that the process unit 8 can be pulled out from the process unit 8 tim forming apparatus, the orientation of the process unit 8 can be changed, and the process unit 8 can be transported without having to change its grip. In other words, when installing the process unit 8, the user opens the VC, opens the front cover 9, which is a part of the movable body 11, and
The handle 14 is grasped and the handle 14 is pulled out in the direction of the arrow to move to a transporting operation, but as is obvious, the process unit on which the handle 14 is formed is not capable of changing its own posture.
When the toner is collected in the cleaning tray provided at the bottom of the photoreceptor drum 1, the toner does not shift in one direction, scatter, or leak out of the process unit.'! Even if a process unit that is not aligned is left outside the image forming apparatus for some reason,
- The bottom shape and center position are straightened so that they do not change.

である。It is also possible to attach the process unit 8 to the movable part 11 that has rotated very slightly, but in this case, the rotation angle θ is set so that the toner movement within the process unit 8 is suppressed, so that the so-called toner rests. It is desirable that it be less than a square. As described above, the shape and position of the process unit and the handle, and the attachment/detachment direction 1 means in the present invention are not limited to the illustrated embodiments, but as long as they have the ability to always enjoy the support posture within the general image forming center, The design can be freely modified.
