Abstract
A first longitudinal registration correcting unit corrects a misalignment of a recording medium in its conveying direction. A lateral registration correcting unit corrects a misalignment of the recording medium in its width direction after the misalignment in the conveying direction is corrected by the first longitudinal registration correcting unit. A second longitudinal registration correcting unit corrects the misalignment of the recording medium in the conveying direction again after the misalignment in the width direction is corrected by the lateral registration correcting unit.
Claims9
A conveying device that conveys a recording medium to an image transfer unit that transfers an image formed on an image carrier to the recording medium, the conveying device comprising:
- a butting member against which a leading edge of the recording medium abuts and opens and closes a conveying path of the recording medium;
- a detecting unit arranged on a downstream side of the butting member in a conveying direction and that detects a leading edge of the recording medium;
- a longitudinal registration correcting unit that corrects misalignment of the recording medium in the conveying direction based on detection by the detecting unit after the butting member corrects a skew of the recording medium;
- and
- a lateral registration correcting unit that corrects a misalignment of the recording medium in its width direction after the butting member corrects a skew of the recording medium, wherein
- the longitudinal registration correcting unit that corrects misalignment of the recording medium in the conveying direction based on the detection by the detecting unit after the lateral registration correcting unit corrects the misalignment of the recording medium in the width direction.
An image forming apparatus comprising:
- a conveying device that conveys a recording medium to an image transfer unit that transfers an image formed on an image carrier to the recording medium, the conveying device including
- a butting member against which a leading edge of the recording medium abuts and opens and closes a conveying path of the recording medium;
- a detecting unit arranged on a downstream side of the butting member in a conveying direction and that detects a leading edge of the recording medium;
- a longitudinal registration correcting unit that corrects the misalignment of the recording medium in the conveying direction based on detection by the detecting unit after the butting member corrects a skew of the recording medium;
- and
- a lateral registration correcting unit that corrects a misalignment of the recording medium in its width direction after the butting member corrects a skew of the recording medium, wherein
- the longitudinal registration correcting unit that corrects misalignment of the recording medium in the conveying direction based on the detection by the detecting unit after the lateral registration correcting unit corrects the misalignment of the recording medium in the width direction.
