Abstract
A curl-correcting device includes a first curl-correcting section and a second curl-correcting section. The first curl-correcting section is disposed on a conveying path along which a recording medium is conveyed in a conveying direction. The first curl-correcting section corrects curl in a recording medium having a first thickness. The second curl-correcting section is disposed on the conveying path either upstream or downstream of the first curl-correcting section in the conveying direction. The second curl-correcting section corrects curl in a recording medium having a second thickness greater than the first thickness.
Claims11
A curl-correcting device comprising:
- a first curl-correcting section disposed on a conveying path along which a recording medium is conveyed in a conveying direction, the first curl-correcting section correcting curl in a recording medium having a first thickness;
- and
- a second curl-correcting section disposed on the conveying path either upstream or downstream of the first curl-correcting section in the conveying direction, the second curl-correcting section correcting curl in a recording medium having a second thickness greater than the first thickness.
An image-forming apparatus comprising:
- an image-forming unit that forms an image on a recording medium by depositing toner thereon;
- a fixing unit that fixes the image on the recording medium by fusing the toner;
- a conveying unit that conveys the recording medium to the image-forming unit and to the fixing unit along a conveying path;
- and
- a curl-correcting device disposed downstream of the fixing unit on the conveying path, the curl-correcting device comprising:
- a first curl-correcting section disposed on the conveying path along which a recording medium is conveyed in a conveying direction, the first curl-correcting section correcting curl in a recording medium having a first thickness;
- and
- a second curl-correcting section disposed on the conveying path either upstream or downstream of the first curl-correcting section in the conveying direction, the second curl-correcting section correcting curl in a recording medium having a second thickness greater than the first thickness.
