It rotates to try to send out the top bag 52a to the right in the figure. At this time, the top bag 52a is sent out without any trouble if it slips between the sheets shown by B, but wrinkles occur in the top bag 52a if it slips between the sheets shown by A.

In general, when a transfer sheet is fed to the transfer area in a superimposed manner, as shown in FIG. 8, one portion a and two portions b and three portions b are stacked. The density of the electric charge that has dropped onto the surface of the portion c is uniform but high. For this reason, since the charge density becomes small in a place where a large number of sheets are stacked, the transfer electric field becomes insufficient and transfer failure occurs. As shown in FIG. 9, some conventional envelopes 52 have a two-layer area b, a three-layer area c, and a four-layer area d. In addition, transfer failure is likely to occur in the area d where the four sheets are overlapped.

まうこともある。Further, in an electrophotographic apparatus, as shown in FIG. 10, a roller fixing apparatus which conveys the transfer paper 52 by pressing and holding it with two rollers 54 and 55 at the time of fixing is often used. Is fixed, the two sheets of paper forming the bag are displaced due to a difference in hardness, a difference in bending between the upper roller and the lower roller, a difference in surface friction coefficient, and the like, and wrinkles are generated. Furthermore, when fixing the envelope with the roller fixing device,
The shear force acting on the two sheets may shift the fold at the end of the envelope.

摩擦係数が異なる紙２を用いている。そして、袋１は摩
擦係数の大きい粗い面２ａ同士を合わせるようにして貼
着され、袋状に形成されている。In FIG. 1, reference numeral 1 denotes a bag formed by gluing the three sides of two rectangular papers 2 around three sides. As shown in FIG. 2, the paper 2 used for the bag 1 is a paper whose one surface is rough with respect to the other surface, that is, a paper 2 having different front and back friction coefficients. The bag 1 is adhered so that the rough surfaces 2a having a large coefficient of friction are joined together, and is formed in a bag shape.

すなわち、袋１の内面が滑らないので、給紙時において
袋１にシワが生ずることが防止される。With this configuration, the paper between the outer surfaces of the bag 1 shown in FIG. 7B is easily slipped, and the paper between the inner surfaces shown as A is opposed by the rough surface 2a, so that the bag 1 is hard to slip. Therefore, when the printing operation is performed by setting the paper feeding cassette 20 in a paper feeding cassette of a printer or a copying machine, the outer surface of the bag 1 slides even when the paper feeding roller 20 rotates, and the paper can be fed in order from the top bag.
That is, since the inner surface of the bag 1 does not slip, wrinkling of the bag 1 during feeding is prevented.

紙時に袋１がシワが生ずることがない。As shown in FIG. 3, after the bag 1 is formed of paper 2 'having substantially the same friction coefficient on the front and back sides, the surface indicated by C is placed on a flat surface, For example, when the bag 1 is pressed by a member (not shown) having a convex portion with a sharp pointed tip, the outer surface of the bag 1 is flat, but the inner surface is engaged with the unevenness, so that the bag 1 is hard to slip. Therefore, similarly to the above-described embodiment, the bag 1 does not wrinkle during paper feeding.

By using No. 2, wrinkles are less likely to occur, and printing is preferably performed on thick paper 12. Further, even when the thick paper 12 is used, since the bag 11 is formed by the thin paper 12a, the thickness is not so large as a whole, so that the transfer electric field is not so weakened.

The overall thickness is uniform and many can be easily stacked. In this embodiment, as shown by the hatched position in the figure, the thick paper 1
2, the entire circumference of the thin paper 12a is glued, and a hole 14 is formed near the flap 13 of the thin paper 12a because the thick paper 12 is a printing surface. Therefore, the thickness of the bag 11 is uniform over the entire area, and the print density is uniform. When the bag 11 is sealed, the flap 13 is folded into thin paper 12a.

シワが生ずることなく、良好な給紙が得られる。According to the first aspect of the present invention, when a plurality of sheets are stacked, the coefficient of friction between the inner surfaces of the sheets forming the bag is larger than the coefficient of friction between the sheets. Even when the sheets are separated from each other without shifting on the inner surface of the sheets, good sheet feeding can be obtained without wrinkles.
