A xerographic developer apparatus wherein the idler end of a hollow and rotatably mounted developer roller is resiliently supported for radial movement by a radially compliant hub. The hub comprises a unitary series of stainless coils that are wound about an axis of rotation of the developer roller. The series of wire coils include a first multi-turn end portion to physically engage the roller's idler end, an opposite multi-turn end portion to engage a bearing that is fixed in position to generally coincide with the roller's axis of rotation, and an intermediate multi-turn portion that is free of physical engagement with either of the roller's idler end or the bearing. The intermediate multi-turn portion resiliently support the roller's idler end for needed radial movement relative to the bearing.
