Abstract: In an image forming apparatus, a rotating body has a follower member that is arranged to confront with a drive member in an axial direction of the drive member. A drive transmitting member transmits drive force from the drive member to the follower member by coupling the drive member and the follower member with each other, while allowing relative positional deviation between the drive member and the follower member on a plane perpendicular to the axial direction of the drive member within a prescribed range. The drive member and the follower member have a drive-member side contact part and a follower-member side contact part, respectively. A making-contact member brings the drive-member side contact part and the follower-member side contact part into contact with each other.

Abstract: The image-forming device includes an image-forming unit, a fixing unit, a pair of first guides, and a pair of second guides. The recording sheet defines a width in a direction perpendicular to a sheet conveying direction. The image-forming unit forms a developing agent image on the recording sheet. The fixing unit includes a heating and a pressure roller. The heating roller heats the recording sheet discharged from the image-forming unit. The pressure roller presses the recording sheet against the heating roller. The heating roller and the pressure roller provide a nip point where the recording sheet is nipped therebetween. The nip point is offset in a thickness direction of the recording sheet from a plane along which the recording sheet is discharged from the image-forming unit. A sheet conveying path is provided from the image-forming unit to the fixing unit. The pair of first guides dispose on the conveying path and configure to contact with an image-forming side of the recording sheet at both widthwise edges thereof, for restraining the recording sheet from being displaced toward the image-forming side. The pair of second guides dispose on the conveying path and configure to contact with the image-forming side of the recording sheet at both widthwise edges thereof for restraining the recording sheet from being displaced toward the image-forming side, a distance between the pair of first guides in the widthwise direction being greater than a distance between the pair of second guides in the widthwise direction, and the pair of second guides being offset from the pair of first guides in the sheet conveying direction.
