Reference numeral 1 denotes a photosensitive drum as an image bearing member, which has a three-layer structure in which a conductive layer, a photoconductive layer, and a surface insulating layer are sequentially stacked. The photosensitive drum 1 is uniformly charged by a primary -1iF electric charger 2 while rotating in the direction of the arrow, and then primary charged by an AC or charge remover 3 whose polarity is opposite to that of the -1iF charger 2 while projecting image light. The charges are removed, and then the lamp 4 is uniformly exposed to light to form an electrostatic latent image corresponding to the projected image light. This electrostatic latent image is developed by the developing device 5, transferred onto the transfer paper P by the transfer device 6, and fixed, thereby completing the copying.

A discharge port 21c for discharging toner from the cleaner 21 is provided. Reference numeral 24 denotes a shutter that fits into the cylindrical portion 21a and a shaft portion 21c provided at the tip of the cylindrical portion and is attached so as to be slidable in the left-right direction.The shutter 24 is provided with a hole 24a. Reference numeral 23 denotes a compression spring that connects the collar 21b provided on the cylindrical portion of the cleaner 21 and the shutter 24.
The shutter 24 is attached between the flange portions 24b of the shutter 24 to always urge the shutter 24 to the right in the figure. Further, the movement of the shutter 24 is regulated by a stopper 21d provided at the tip of the shaft portion 21c. Reference numeral 22 moves the toner to the right by rotating it with a screw. A toner collection container 26 is supported and fixed by a support member 27e provided on the front door 27 and a leaf spring 25. Further, the protrusion 27b comes into contact with the flange portion 24b of the shutter 24 when the front door 27 is closed. A conveyance roller 29 is supported by a bearing 31, and forms a conveyance section that conveys the transfer paper to the fixing device. 3
Reference numeral 2.33 denotes a side plate and a bottom plate, which constitute a casing that supports the Ki optical drum, the cleaner device, the transport section, and the like.

The hole 21c provided in the cylindrical portion 21a of 1 and the shutter 24
The holes 24a provided in the toners are aligned with each other, and the toner sent by the rotation of the screw 22 falls naturally through these holes and is collected in the toner collection container 26. When the front door is open, there is no shutter mechanism on the protrusion 27b that serves as the joint of the toner collection device.
There was a problem in that the collected toner would scatter when the door was opened and closed.

しまうのを防ぐことができる。FIG. 1 shows an embodiment of the present invention, which differs from the conventional one in that a shutter 102 is provided at the tip of the protrusion 27b of the front door to slide on the inside of the flange 27C1 and the protrusion 27b.
A shutter mechanism consisting of a compression spring 101 is attached to bias the spring to the left in the figure. A compression spring 101 is provided between the shutter 102 and the front door 101. When the front door is in a closed state, the flange 24b of the shutter 24 is pushed by the flange 27c provided at the tip of the projection 27b, and the hole 21 provided in the cylindrical portion 21a of the cleaner 21 is pushed.
c and the hole 24a provided in the shutter match, and the screw 2
The toner sent by the rotation of step 2 falls naturally. The shutter 102 is pushed to the right in the figure by a stopper 21d provided on the shaft portion 21c of the cleaner 21, and a hole 27d provided at the bottom of the protrusion 27 allows the toner that has fallen through the holes 21c and 24a to fall to the toner collection container 28. You will be able to do it. When the front door is open, the shutter 102 is released from the restraints by the cleaner shaft 21c and the stopper 21d, and the shutter 102 is pushed to the left in the figure by the compression spring 101 and stops when it comes into contact with the flange 27c of the i-protrusion 27b from the inside. , it is possible to prevent the toner collected in the toner collection container 28 from going backwards through the hole 27d provided in the protrusion 27C and scattering.

ータ、もしくはソレノイド等で行なっても良い。In this embodiment, the shutter 102 has a closing mechanism that utilizes restoring force due to spring compression, or is equipped with a sensor that detects the opening and closing of the front door, and the sensor determines whether the front door is open or closed and indicates whether the door is closed. The shutter is opened when the door is open, and the shutter is closed when the door is open, and the shutter may be driven by a motor or a solenoid.

。In addition, the shutter mechanism is modified as shown in FIG. 3, and the shutter 102' can move in the direction of arrow a centering on the glaze 103. If the cleaner end 21c and stopper 21d do not touch each other due to the hair spring 101', is urged against and abuts against the flange 21C of the protrusion 27b. This can prevent toner from scattering when the front door is open, so it is good to modify the shutter in this way.

な行為を無くすことにも効果がある。As explained above, by providing a shutter mechanism in the joint part on the toner collection container side of the toner collection device, it is effective to prevent toner from scattering from the toner collection device due to opening and closing of the front door. It is also effective in eliminating the unnecessary work of cleaning up toner that has been splashed or splashed on a part of the body.
