Description

DETAILED DESCRIPTION OF THE INVENTION

[0002]

2. Description of the Related Art In recent years, digitization has advanced in electrophotographic apparatuses, and digital copying machines have become widespread. In a digital copying machine, a reversal development method is mainly used, and in a transfer process, the polarity of a photoconductor and the polarity of a transfer member such as a transfer corona are reversed.

Therefore, the polarity of the transfer object such as paper and the photoreceptor is reversed, and both are attracted and adsorbed. Therefore, it is necessary to devise a method for separating the transfer target from the photoreceptor.

Conventional laser printers and the like often have a slow process speed, are separated by the stiffness of paper, and are provided with a peeling member such as a transfer corona as an auxiliary means to remove electricity from the paper. However, digital copiers with high process speeds use organic photoconductors with relatively low sensitivity,
The diameter of the photoreceptor increases, and it is difficult to separate the paper by the waist.
Therefore, a method has been proposed in which a photosensitive member is formed into a belt shape to separate the photosensitive member by increasing the curvature of the photosensitive member in a transfer portion, or a method in which a belt is used as a transfer member and paper is electrostatically attracted to the belt side.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 is a configuration diagram illustrating the image forming unit K. In the drawing, reference numeral 1 denotes a photoconductor as an image carrier, and the photoconductor 1 is provided around the photoconductor 1 in order along the rotation direction thereof.
A charger 2 for uniformly charging the surface of the photoconductor 1 to a surface potential of -500 to -800 V; an exposure unit 3 for forming an electrostatic latent image on the surface of the photoconductor 1; Developing device 4 for making a visible image, transfer device 5 for transferring a visible image to paper P as a material to be transferred, cleaning device 6 for removing residual toner on photoconductor 1, removing residual potential on photoconductor 1 The static elimination means 7 is provided.

The transfer device 5 has a belt unit 9. The belt unit 9 has a transfer belt 12 as a running member that is stretched between the support rollers 10 and 11. The transfer belt 12 has a volume resistance of 10 ⁸ to 10 ¹² Ω ·
The paper P travels while being pressed against the photoreceptor 1 by an elastic belt of cm, and conveys a sheet P as a transfer target.

The support roller 10 on the downstream side in the transport direction of the paper P
Denotes a driving roller (hereinafter, the supporting roller 10 is referred to as a driving roller). The driving of the driving roller 10 causes the transfer belt 12 to run at substantially the same moving speed as the photosensitive member 1.

A power supply roller 14 facing the photoreceptor 1 is in contact with the back side of the transfer belt 12. Feed roller 1
Reference numeral 4 denotes a conductive elastic roller having a volume resistance of 10 ² to 10 ⁷ Ω · cm, and a bias (+3
A high-voltage power supply 15 for applying a voltage of 0.00 to 5 kV) is connected.

A guide member 17 for guiding the sheet P and a fixing device 18 as a fixing unit for fixing the toner image transferred on the sheet P to the sheet P are provided in the direction in which the transfer belt 12 is carried out.

At the time of printing, the surface of the photoconductor 1 is uniformly charged to a surface potential of -500 to -800 V by the charging charger 2, and the charged surface of the photoconductor 1 is exposed to the electrostatic latent image by the exposure means 3. Is formed. The electrostatic latent image is sent to the developing device 4 by the rotation of the photoconductor 1, and the electrostatic latent image is visualized by supplying negatively charged toner from the developing device 4.

On the other hand, at this time, the paper P is fed between the photosensitive member 1 and the transfer belt 12 by the movement of the transfer belt 12, and a bias (+300 to 5 kV) is applied to the transfer belt 12 by the high-voltage power supply 15. Is done.
Thereby, the visible image on the photoreceptor 1 is transferred to the paper P,
The sheet P to which the visible image has been transferred is carried out by the movement of the transfer belt 12 and sent to the fixing device 18 via the guide member 17 so that the visible image is fixed on the sheet P.

By the way, in normal printing, the transfer belt 1
The photosensitive member 1 and the photosensitive member 1 are driven in a state of being separated from each other, and are brought into contact with each other after reaching approximately the same surface moving speed. It is transported and reaches the transfer nip area.

The paper P passing through the transfer nip area is electrostatically attracted onto the transfer belt 12,
Is large (usually φ12 to 4
0) Therefore, at the most downstream side of the belt unit 9, the leading end of the sheet P separates from the transfer belt 12 and is conveyed to the fixing device 18 through the guide member 17.

FIG. 2 shows the guide member 17.
The guide member 17 is formed at a first guide portion 17a inclined downward from the carry-out side of the transfer belt 12 and a second guide portion formed continuously at a lower end portion of the first guide portion 17a and inclined upward. And is projected downward in a concave shape.

When the sheet P is a thin sheet, the sheet P is conveyed to the fixing device 18 in a state of sticking to the guide member 17. Even after the leading end of the sheet P is separated from the transfer belt 12, the sheet P is It is guided downward by the guide member 17. Therefore, the rear end of the sheet P is smoothly separated from the transfer belt 12 and does not jump.

[0034]

[Table 1]

Table 1 shows that, as shown in FIG.
Is changed by changing the inclination angle θ1 of the first guide portion 17a.
3 shows the degree of disturbance of the image at the rear end of the image.

The experimental machine has a process speed of 400 mm /
sec, the transfer belt 12 has a resistance value of 10e10Ω · cm.
Was used. The paper P is 50 g paper, 64 g
The results of printing 1000 sheets under each condition using paper, 127 g paper, and 200 g paper are shown.

According to this, the inclination angle θ of the first guide portion 17a of the guide member 17 is set at 30 ° from the point where the belt curvature starts with respect to the transport direction of the sheet P on the transfer belt 12.
When the angle is set to the lower side, the disturbance of the 64 g paper is almost invisible, and when the angle is set to the lower side by 40 degrees or more, the image disturbance at the rear end can be obscure even in the thin 50 g paper.

The first guide portion 17 of the guide member 17
If the initial angle a is too large, the rear end of the sheet P cannot be guided, and the effect is reduced. According to the experiment, the image disturbance was not conspicuous until the first inclination angle θ1 of the guide portion 17a of the guide member 17 was 70 °, but when the inclination angle θ1 was more than 70 °, the image disturbance tended to occur.

In the case of thick paper, the guide member 1
7 was not induced, so no significant change was observed, but slight image disturbance was observed throughout. FIG. 4 shows a guide member 21 according to a second embodiment of the present invention.

In the first embodiment, the bottom of the guide member 17 is formed in an arc shape. However, in the second embodiment, the bottom of the guide member 21 is formed in a flat shape, and the entire shape is square. Make up. With this shape, the same operation and effect as in the first embodiment can be obtained.

FIG. 5 shows a guide member 25 according to a third embodiment of the present invention. This guide member 25
Is composed of a combination of a support member 31 for supporting the belt unit 9 and a flat guide plate 32.

A first guide portion, a guide plate 3, for guiding the sheet P downward by the inclined end surface 31a of the support member 31
Reference numeral 2 denotes a second guide section for guiding the sheet P upward.

FIGS. 6 and 7 show a fourth embodiment of the present invention. When the thick paper (127 g or more) is peeled from the transfer belt 12, the point at which the paper P is peeled is
Near the point 29 where the curvature of the drive roller 10 on the most downstream side of the belt unit 9 starts, the direction of the paper P peeled off from the transfer belt 12 is also close to the paper conveyance direction on the transfer belt 12.

Even in such a state, the halftone disturbance in the latter half of the paper P is slightly generated as shown in the experimental results in Table 1, so the following configuration was adopted. A point 29 where the transfer belt 12 that has conveyed the paper P contacts the drive roller 10 of the transfer belt 12 and a paper entrance 36 of the fixing device 35
And a straight line 38 drawn from the point 29 to the downstream side of the belt in the transport direction of the sheet P adsorbed on the transfer belt 12 is 20 ° to 50 °.
° range.

That is, the fixing device 35 is located above the transfer belt 12, and the guide member 40 is provided between the belt unit 9 and the fixing device 35 at an angle. According to this configuration, the leading end of the sheet P that has passed through the belt unit 9 abuts on the guide member 40 with the rear end remaining on the transfer belt 12, whereby the sheet P is entirely lifted upward. .

Therefore, as the stiffness of the paper P increases, the rear end of the paper P on the transfer belt 12 is lifted upward, and before the rear end of the paper P reaches the most downstream side of the transfer belt 12. The suction force of the transfer belt 12 is weakened, and the paper P
Is less likely to be disturbed in the latter half of the image.

[0047]

[Table 2]

Table 2 shows a comparison between the occurrence rate of the jam and the degree of disturbance of the image on the second half side of the sheet P by changing the inclination angle θ2 of the guide member 40. Paper P is 127g paper,
Use 200 g paper, 1000 for each condition
Printed sheet by sheet.

According to this, the angle θ2 of the guide member 40
The larger the value is, the less the disturbance of the image becomes, but the jam rate increases. Regardless of the type of paper, the range of angles at which the jam rate is less than 5% and which is effective for image disorder is 20 ° to 50 °. ° to 30 °.

FIG. 8 shows a fifth embodiment of the present invention. This embodiment is a combination of the first embodiment and the fourth embodiment.

That is, the fixing device 35 is provided above the transfer belt 12 in the carry-out direction, and the fixing device 35 and the transfer belt 12
The guide member 17 shown in the first embodiment is provided in a state where the inclination angle of the second guide portion 17b is high.

The thin paper is guided by the guide member 17 between the belt unit 9 and the fixing device 35, and the thick paper is weakened because the stiffness of the paper weakens the adsorbing force while the rear end portion is on the transfer belt 12. Irrespective of the above, the image disturbance at the rear end of the paper can be reduced.

In the experiment, the first guide portion 1 of the guide member 17 was used.
7a was set to 40 °, and the position of the fixing device 35 was set to be obliquely upward by 25 ° with respect to the paper conveyance direction on the transfer belt 12, and 50 g paper, 64 g paper, and 127 g
In all of the paper and the 200 g paper, the disturbance of the image at the trailing edge of the paper was reduced and became inconspicuous.

FIG. 9 and FIG. 10 are views showing a sixth embodiment of the present invention. In this embodiment, after the leading end of the paper P that has passed through the belt unit 9 enters the fixing device 18, the cam 51 serving as a lifting device between the belt unit 9 and the fixing device 18 is moved upward from the paper transport path. It has a mechanism for rotating.

When the leading end P1 of the sheet P is separated from the transfer belt 12, the cam 51 is lowered and kept horizontal as shown in FIG. 9A, and serves as a normal sheet transport guide. After the leading edge P1 of the sheet enters the fixing device 18, the cam 51 is rotated clockwise as shown in FIG. 9B to push the sheet P upward, thereby causing the belt unit 9 to move upward.
The second half P2 of the upper sheet is pushed upward.

Then, the rear end P3 of the sheet P is
9 and passes over the cam 51, the cam 51 is rotated clockwise as shown in FIG. 9C and returns to the initial position again, after which the leading edge of the next sheet P passes. This operation is repeated.

The operation timing of the cam 51 is such that the paper P is moved upward after the leading edge of the paper P enters the fixing device 18 and after the trailing edge of the paper P passes through the transfer nip. This is preferable because there is no fear of causing blurring.

FIG. 10 is a flowchart showing the operation of the cam 51. That is, after the cam 51 is rotated downward, the printing operation is started (step ST1). Next, it is determined whether the paper P is conveyed by the movement of the transfer belt 12 and the trailing end is separated from the transfer nip (step ST2). If the trailing edge of the paper P is separated from the transfer nip, it is determined whether the leading edge of the paper P has entered the fixing device 18 (step ST3). When it is determined that the leading end of the sheet P has entered the fixing device 18, the cam 51 rotates upward (step ST4). Next, it is determined whether or not the rear end of the paper P has passed over the cam 51 (step ST).
5) If it passes, the cam 51 is moved downward (step ST6).

[0059]

[Table 3]

Table 3 shows a comparison of the degree of image distortion when the present invention is applied and when the present invention is not applied, and shows which paper type (50 g paper, 64 g paper, 127 g paper, 200 g paper).
Also showed an effect.

FIG. 11 shows another embodiment of the lifting means. In this embodiment, a plate-like lifting plate 55 is used as the lifting means. FIG. 12 further illustrates the lifting means.
In this embodiment, a cam member 6 having a long depth in the width direction of a sheet is used as a lifting means.
0 is used.

According to this embodiment, partial image disturbance due to friction between the cam member 60 and the sheet is reduced, which is more preferable. FIG. 13 shows still another embodiment of the lifting means. In this embodiment, a disk-shaped lifting member 65 which rotates eccentrically is used as the lifting means.

According to this embodiment, the same effect as described above can be obtained by rotating the cam 51 at the same timing as that shown in FIGS. 13A to 13C.

[0064]

As described above, according to the present invention, the guide means for guiding the object to be transferred conveyed from the traveling member is inclined obliquely downward from the discharge end side of the traveling member toward the traveling direction of the traveling member. The first guide portion and the second guide portion formed continuously with the first guide portion and inclined obliquely upward are formed even after the leading end of the transfer object is separated from the traveling member. The transfer member (thin object) is guided downward by the first guide portion, and the rear end of the transfer member can be smoothly separated from the traveling member.

Therefore, even a thin paper sheet whose separation point from the traveling member is slow and which is fed downward from the normal conveyance path can be smoothly conveyed to the fixing device without the rear end of the thin paper jumping.

Further, the guide means for guiding the object to be transferred carried out from the traveling member of the transfer means in a predetermined direction is inclined obliquely upward from the discharge end side of the traveling member toward the traveling direction of the traveling member. In addition, the tip of the transferred object (thick material) is brought into contact with the guide means to lift the transferred object as a whole upwardly, thereby reducing the attraction force of the traveling member to the rear end of the transferred object.

Therefore, it is possible to easily peel off the rear end portion of the transfer object from the traveling member, prevent unnecessary discharge and splashing, and reduce disturbance of the image. Further, in a state in which the leading end of the transferred object is unloaded from the traveling member and the rear end of the transferred object is on the traveling member, the push-up which pushes up the rear end side of the transferred object in a direction away from the traveling member Since the means is provided, it is possible to reduce the attraction force of the traveling member to the rear end portion of the transfer-receiving member and smoothly separate the traveling member, prevent unnecessary discharge and splashing, and reduce disturbance of the image.
