摘要： A transfer device includes a nip forming member to contact a surface of an image bearing member to form a transfer nip therebetween, a pressing device, and a nip pressure changing device. The pressing device includes a plurality of elastic members, to produce a contact pressure between the nip forming member and the image bearing member according to a restoring force of at least one of the elastic members upon deformation of the elastic member. The nip pressure changing device changes an amount of elastic deformation of the elastic member between at least two stages to change a nip pressure of the transfer nip. While the contact pressure is produced by one of the elastic members, the nip pressure changing device changes the amount of elastic deformation of a different elastic member, different from the one that produces the contact pressure, to change the nip pressure of the transfer nip.

摘要： An image forming apparatus includes a print head, an endless belt, a pressure roller, and a controller. The print head is configured to eject droplets of ink from multiple nozzles onto a recording sheet. The endless belt is stretched around at least first and second rollers, and is configured to convey the recording sheet placed on an outer surface thereof. The pressure roller is configured to exert pressure against the outer surface of the endless belt. The controller is configured to move the endless belt into a correcting position where the pressure roller meets a given portion of the endless belt. The given portion of the endless belt is previously retained in contact with the first roller and develops deformation due to the previous retention. The pressure exerted by the pressure roller corrects the deformation while the endless belt is in the correcting position.
