Abstract

PURPOSE:To make a pressing force uniform and enhance the fitness to clean well a drum throughout the overall width of the drum, by dividing a blade supporting member so that a flexible blade forms a pressing force distribution in the lengthwise direction. CONSTITUTION:A flexible blade member 1 consisting of rubber or the like is superposed upon a blade supporting member 10 and has rear edges 1b and 10b held between holders 3 and 4. The supporting member 10 is so divided that the pressing force distribution is formed on the blade member 1 in the lengthwise direction and the width of divided pieces is reduced gradually from left and right parts toward the center part. The blade 1 is pressed to the drum by a spring, and the pressing force and the flexural rigidity are higher in the position of the divided piece having a longer width to compensate for a weaker pressing force in left and right parts than the center part. Thus, the pressing force is made uniform to enhance the fitness, and the drum is cleaned well throughout the overall width of the drum.

PRIOR ART In general, in a powder image transfer type electronic copying machine, an electrostatic latent image is formed on the photosensitive layer while rotating a photosensitive drum having a photoconductive photosensitive layer on the surface [7. A toner image obtained by developing with toner. is transferred onto the sheet. Residual toner adheres to the surface of the photoreceptor drum after the transfer process is completed. Conventionally, in order to remove such residual toner, the first
As shown in the figure, a flexible blade member (1) made of rubber, a metal thin plate, a synthetic resin thin plate, etc. is attached to the surface of the photoreceptor drum (2). The flexible blade (1) is pressed against the drum (2) so that the direction in which it moves and the angle formed by the flexible blade (1) is an obtuse angle (or an acute angle in some cases).
A blade cleaning device is used to remove residual toner near the surface of the -8-machi flexible blade member (1
) can hold the rear edge side with holders (3) and (4),
The holders (3) and (4) are connected to the rotating shaft of the drum (2) and 7.
It was attached to a mounting member (7) on an arm (6) rotatably supported on a horizontal shaft (5), and a hook was passed between the free end of the arm (6) and the fixed pin (8). Due to the bias of the spring (9), the flexible blade member (1) is attached to the drum (2).
It is made to be pressed against the surface.

In order to completely remove the residual toner on the outer surface of the drum (2), it is necessary to warm the flexible blade member (1) over the entire width of the surface of the drum (2) so that it makes uniform EE contact. The higher the level, the greater the removal effect. However, if the pressure contact force is increased, not only will the JF wear and QJ of the leading edge (LA) of the 'T flexible brake 1 member 1) become larger, but also the +p ratio of the drum (2) and the loss/loss. Become more personable, and the lifespan of both is K<i
On the other hand, in a conventional blade cleaning device, the fulcrum of the pressure weld is set to a flexible blade IM≦material ( 1), it is provided in the center of the holders (3) and (4) that support the flexible blade member (11

Conventionally, in order to uniformly remove residual toner, when the pressing force of the flexible blade member (1) against the drum (2) is strengthened, the pressing force at the center of the flexible blade becomes excessive.
The life of the flexible blade member (1) and the drum (2) is shortened due to wear and damage. In addition, flexible blade members (
1) If the blade is made of a thin sheet of synthetic resin, the blade support member (10) is attached to one side of the flexible blade member (1) (the dotted line in Figure 1). ) may be provided.

This makes it possible for the flexible blade member fil to follow the continuous displacement of the drum (2) surface in an effective manner, even though the fS relative to the drum (2) surface change becomes worse. Therefore, residual toner adhering to the distorted portions of the drum surface cannot be removed completely, resulting in poor cleaning performance.

Therefore, the larger the division width of the blade support member (lO), the more flexible the flexible blade member <1), the more the holder (3),
(4) The pressure contact force and bending rigidity reinforcement effect indirectly transmitted through t4 becomes large, and the flexible blade member (11
This compensates for the fact that the pressure contact force against the surface of the photoreceptor drum (2) on both sides of (i) is weaker than that at the center.
The non-uniform pressure contact force between the long squares of the flexible blade member (1) is eliminated, and the 6f flexible blade member (1)
The leading edge (1a) of the photosensitive drum (2) is uniformly pressed against the surface of the photosensitive drum (2), and residual toner can be removed over the entire area of the drum (2).

Furthermore, since the blade support member (lO) has a divided shape, the blade support member (lO) can move independently.
1 partial displacement can be reliably absorbed. Therefore, even if the photoreceptor drum (2) is distorted and displaced due to rotation, the Loe flexible blade (1) can easily follow this displacement.
1) The leading edge (1a) becomes more familiar with the surface of the drum (2), and the cleaning performance is greatly improved.

Figure 4 shows the second actual example, in which the blade support member (10) is equally spaced by the notch (11):
It is divided into threads and has a concave shape with a curved cut in the center, and protrudes from the front edges (3a) and (4a) of the holders (3) and (4) of the blade support member (1o). (2) The length changes from the right side to the center in a substantially quadratic curve I7, which gradually decreases. In this case, the divided shape of the blade support member (10) is different from fs, and the same effect as the actual relaxation example of $1 can be obtained.
