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.

摘要： The transfer assembly includes a belt, a transfer device, a contact-and-separation device including a retainer, and a first vibration absorber. The transfer device contacts an image bearer via the belt to form a transfer nip portion between the image bearer and the belt and to transfer the toner image onto one of a surface of the belt and a recording medium carried on the surface of the belt. The contact-and-separation device moves the transfer device to contact and separate from the image bearer. The retainer is pivotally supported by a swingable shaft and movable in a first direction in which the transfer device approaches the image bearer and in a second direction opposite to the first direction in which the transfer device separates from the image bearer, to hold the transfer device. The first vibration absorber absorbs vibration transmitted from the swingable shaft to the transfer device via the retainer.

摘要： A transfer device includes a pressed unit, a rotatable roller, and a pressing member. The pressed unit is movably supported and includes a first non-rotatable shaft portion and a second non-rotatable shaft portion. The rotatable roller is rotatably supported by the first non-rotatable shaft portion of the pressed unit. The pressing member contacts the second non-rotatable shaft portion of the pressed unit and presses the pressed unit. The second non-rotatable shaft portion has an axial center aligned with an axial center of the first non-rotatable shaft portion.
