An experimental and analytical investigation has been performed on vibration induced in a driving mechanism of a photoconductor drum in a color laser printer. From results of the investigation, the following points were deduced : (1) flywheel driven by a pulley through a belt caused forced and whirling vibrations. (2) An eccentricity between a shaft and the pulley attached to the photoreceptor drum induced a vertical harmonic pull force to the flywheel through the belt and caused the vertical forced vibration of the flywheel. The driver must be constructed to be small eccentricity of the pulley to the shaft and enough static pull force of the belt. (3) Another vibration was the whirling vibration due to dry friction in a journal bearing which supports the flywheel. The vibration is suppressed under condition of high damping, low friction, and small air gap of the journal dry bearing.
