定着器３４へと導かれる。A half-moon-shaped feeding roller 8 is provided in the vicinity of the separating claw 7 and the reference member 4 at one end of a feeding shaft 10 which penetrates a shaft portion 9a protruding from a frame 9 so as to face the upper surface of the sheet material 2. It is installed. A clutch 11 is provided at the other end of the feeding shaft.
Also, the feeding gear 12 is mounted and drivingly connected to the motor 13 via the idler gear train. On the frame 9 to which the motor 13 and idler gears are mounted, the reference plate 14 is installed at substantially the same position as the contact surface of the reference members 4 and 5 in the sheet material storage cassette in the lateral direction. This reference plate is usually made of a polished steel plate such as a SUS material because the side edges of the sheet material slide in contact with each other. In the case of the present drawing, in the vicinity of the reference plate 14, two conveyance rollers penetrate substantially perpendicularly to the reference plate and face the conveyance roller 15 on the side near the load image forming drum 30 connected to the drive system. The skew feed roller 17 is held by the roller holder 19 so that its axis is directed to the reference plate 14 side at an angle of 0, and is pressurized by the pressure spring 21 to a predetermined pressure. Further, the skew feed roller 18, the roller holder 20, and the conveying roller 16 on the side far from the image forming drum 30 are also provided.
The pressure spring 22 is mounted in a similar relationship. Further, on the reference plate 14, guides 22 and 23 for guiding the sheet material to the conveying roller 16, a guide 24 for guiding the sheet material to the conveying roller 15,
25, guides 26, 2 for guiding the image forming drum 30
7 is formed. Many of these guides often use the outsert forming method in order to improve the adhesion to the reference plate. On the other hand, as the guide 28 in the portion other than the reference vicinity, either gold or mold can be used. Further, the image forming drum 30 and the drum 3 are provided on the downstream side of the conveyance.
A transfer roller 29 which is in pressure contact with 0 is mounted, and is guided to a fixing roller 32 and a fixing device 34 having a pressure roller 33 via a conveyance guide 31.

At the initial position A of the sheet material, the side edge of the sheet material is the reference plate 1
It is assumed that there is an interval of S 1 between 4 and 4. The sheet material is sandwiched between the conveying rollers 15 and 16 and the oblique feeding rollers 17 and 18, but the conveying direction of the sheet material is the D direction because the oblique feeding roller forms a mounting angle of 0. This is separated into a downstream component Dy and a lateral component Dx. That is, the sheet material having the distance S 1 from the reference plate moves to the position B where the distance is S 2 (S 2 <S 1 ) as the conveyance progresses. Eventually, the sheet material is conveyed to the downstream side while hitting the side edge of the sheet with the reference plate 14 and receiving the effect -Dx from the reference plate and hitting the sheet.

９のシート材２はその状態にあることを示す。However, in the above-described conventional example, the conventional concept is followed in the relative speed difference, stop, and start timing of each transport roller in the transport system including the feeding roller. There was a flaw. That is, in FIG. 9, the slack portion 2a is likely to occur in the sheet material 2 between the pair of conveying rollers 15 and the obliquely feeding rollers 17 and the pair of conveying rollers 16 and the obliquely feeding rollers 18. As the cause,
(1) The conveyance speed of the conveyance roller 16 is the conveyance roller 15
Faster than the transport speed. (2) At the timing of stopping the sheet material, the conveyance roller 15 is more than the conveyance roller 16
Stops earlier. (3) The conveyance roller 16 is activated earlier than the conveyance roller 15 at the activation timing of the sheet material. In this one-sided transport system, the only ones that hold and restrain the sheet material are the transport roller and the skew feed roller pair near the reference plate 14. Therefore, when a slack is generated in the sheet material 2, since the anti-reference plate side of the sheet material is not restrained, the sheet material expands in the direction in which the slack is alleviated due to the stiffness of the sheet material. The sheet material 2 in FIG. 9 is shown in that state.

ことになる。In such a state, the posture of the sheet material is not properly slackened, and the leading edge portion when one side end portion of the sheet material is applied to the reference plate, that is, the position E of the chain double-dashed line in FIG. It is displaced to a position F inclined by a certain angle 2. Therefore, if the sheet material rushes into the image forming drum 30 as it is, an image transfer body such as toner is obliquely transferred to the sheet material, resulting in deterioration of printing accuracy.

とができる。The operation of the above structure will be described with reference to FIG. The sheet material is conveyed from the entrance guides 22 and 23 via the conveyance rollers 16 and 15, and the sheet material is stopped after the leading edge cuts off the registration sensor 55. First, the conveying roller 16 on the upstream side is stopped by Δt 1 after the cut time is set to to, and the clutch 52 is stopped. Next, the clutch 53 of the transport roller 15 on the downstream side changes from to to Δ.
The stop operation is applied at the timing t 2 (Δt, <Δt 2 ). The stop sequence with the above-mentioned time difference is the same when the sheet material is fed from the expansion feeding portion, and the stop timing of the transport roller 40 is to stop the clutch 51 after Δt 1 from to. . As described above, in the stopping operation, the upstream transport rollers are stopped earlier than the downstream transport rollers, so that the slack in the sheet material between the transport rollers can be eliminated. Further, in the sequence at the time of start, the conveying roller 15 closest to the image forming drum is first activated, and then the upstream conveying roller 16 is activated after Δt 3 . The same applies to the transport roller 40 of the extension feeding unit. In this way, by activating the transport rollers on the downstream side at the start, the sheet material can be guided to the image forming drum 30 without causing slack in the sheet material between the transport rollers.

上が図れるものである。As described above, in the image forming apparatus using the one-side separation and one-side butting and conveying method, the sheet material conveying speed of the plurality of conveying rollers including the feeding roller is the upstream conveying roller and the sheet conveying speed is the downstream conveying roller. The speed control means is used so as not to exceed the rollers, but the stop timing of the transport roller upstream of the transport roller closest to the image forming unit is slightly earlier than the stop timing of the transport roller closest to the transport roller in the vicinity of the image forming unit. At the start, the start timing of the nearest conveyance roller is set earlier than the start timing of the upstream conveyance roller, or both of them are exercised so that slack does not occur between the conveyance rollers of the sheet material. It is possible to hit the plate and carry it to the downstream side. Therefore, the sheet material always enters the image forming portion in the correct posture, so that the image printing on the sheet material is correctly performed and the printing accuracy can be stably improved.
