Patent ID: 7885558

Claim:
An image-forming device comprising: a housing; an image-carrying member that carries a developer image; a conveying unit that comprises a driving roller having a rotation shaft to be rotatable thereabout, a tension roller disposed in spaced-apart relation with the driving roller, and an endless belt supported between the driving roller and the tension roller and moved circularly by the driving roller, the endless belt having an area in confrontation with the image-carrying member and conveying a recording sheet placed thereon; a transferring unit that is disposed in confrontation with the image-carrying member with the area of the endless belt interposed therebetween and configured to transfer the developer image on the image-carrying member to the endless belt in a first mode and to the recording sheet placed on the endless belt in a second mode; an optical sensor that is disposed near the driving roller and operable in the first mode to detect the developer image on the endless belt; a ground connector that is electrically grounded; a first connection member that has a first electrical resistance and is connected between the driving roller and the ground connector to allow electrical charges to flow therebetween; and a second connection member that has a second electrical resistance and is connected between the endless belt and ground connector to allow electrical charges to flow therebetween, the first electrical resistance being less than the second electrical resistance.
