[0075] figure 1 The main part of the electrophotographic image forming apparatus according to the first embodiment of the present invention is shown. In this image forming apparatus X, a transfer conveyor mechanism 1 is provided. This transfer belt mechanism 1 has: on one side ( figure 1 The left side in the center) is supported as a freely rotatable drive roller 11; on the other side ( figure 1 The center is the right side) is supported as a freely rotatable driven roller 12; it is erected between the two rollers 11, 12 along the figure 1 The endless transfer conveyor belt 13 as a paper carrier driven in the arrow Z direction shown in , makes the recording paper P as a paper electrostatically adsorbed on the surface of the transfer conveyor belt 13, and the positioning roller 10 as a positioning unit , 10 The supplied recording paper P is conveyed from the other side (upstream side) to one side (downstream side). The above-mentioned registration rollers 10, 10 are mean...

[0124] In the first embodiment described above, the line sensor 51 detects only the edge position of the recording paper P. As shown in FIG. On the other hand, in the second embodiment, it is changed so that the edge position of the recording paper P is detected at two places in the recording paper transport direction, and the skewed state of the recording paper P can also be detected. This embodiment will be described below. In addition, the same reference numerals are attached to the same components as those in the first embodiment, and the description will mainly focus on differences.
[0125] Figure 11 It is a schematic diagram showing the peripheral structure of the first and second photosensitive drums in the second embodiment. Figure 12 It is a plan view seen from above the transfer conveyor belt to illustrate the skewed state of the recording paper.
[0126] The line sensor 51 detects the edge position of the recording paper P conveyed to the transfer point G at tw...

[0148] In addition, the meaning of the dotted line and the solid line of the reading timing of the line sensor 51 are the same as those of the reference Figure 10 The same as the first embodiment described.
[0149] Furthermore, in the image forming apparatus X of the second embodiment, color registration correction control is also performed. That is, in the data storage section 406 of the image forming apparatus X, image forming positions to the other photosensitive drums 3b-3d for correcting the image forming positions to the other photosensitive drums 3b-3d with respect to the reference photosensitive drum (for example, the first photosensitive drum 3a on the most upstream side) are stored in advance. (time series) data. And, based on the data and the detection results of the edge position and skew state of the recording paper P under the first and second detection points R1 and R2 by the line sensor 51, the image position and image forming area formed on each photosensit...
