IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes an image bearer, a nip forming device, a contact-and-separation device, a thickness information retrieving device, and a controller. The contact-and-separation device moves the image bearer and the nip forming device to contact and separate from each other. The controller controls the contact-and-separation device based on information on a thickness of a recording medium obtained by the thickness information retrieving device such that in a case in which a thickness of a preceding recording medium and a thickness of a successive recording medium are different in continuous printing in which a plurality of recording media is printed out continuously, the contact-and-separation device adjusts a space between the image bearer and the nip forming device when the preceding recording medium exits the transfer nip to a preset size corresponding to the thickness of the successive recording medium that enters the transfer nip.

主权项

1. An image forming apparatus, comprising:
an image bearer to bear a toner image on a surface of the image bearer; a nip forming device to contact the image bearer to form a transfer nip between the nip forming device and the image bearer and interpose a recording medium therebetween to transfer the toner image from the image bearer onto the recording medium in the transfer nip; a contact-and-separation device to move the image bearer and the nip forming device to contact and separate from each other; a thickness information retrieving device to obtain information on a thickness of the recording medium; a controller to control the contact-and-separation device based on the information on the thickness of the recording medium such that in a case in which a thickness of a preceding recording medium and a thickness of a successive recording medium are different in continuous printing in which a plurality of recording media is printed out continuously, the contact-and-separation device adjusts a space between the image bearer and the nip forming device when the preceding recording medium exits the transfer nip to a preset size corresponding to the thickness of the successive recording medium that enters the transfer nip.
