    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： An image forming apparatus includes an image carrier that carries a toner image; a transfer member that forms a transfer nip between the transfer member and the image carrier; and a power supply capable of outputting a superimposed transfer bias in which an alternating current component is superimposed onto a direct current component. The toner image on the image carrier is transferred onto a recording medium in the transfer nip by the superimposed transfer bias or a direct current bias consisting of the direct current component output by the power supply. The apparatus also includes a controller that controls the power supply so that an output target value of the direct current component when the direct current component rises up is larger than an output target value of the direct current component when the toner image is transferred onto the recording medium.

    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.
