ABSTRACT:
A high precision image recording apparatus includes an electrophotographic device having at least a photosensitive drum and an exposure unit, for forming a toner image on the surface of the photosensitive drum; a recording sheet feed/transport unit for feeding and transporting a recording sheet to which the toner image formed on the surface of the photosensitive drum is transferred; a transfer unit for transferring the toner image on the photosensitive drum to the recording sheet fed and transported by the recording sheet feed/transport unit; and a drive unit for driving the photosensitive drum and recording sheet feed/transport unit. The drive unit is provided with a motor coupled to the photosensitive drum via a rotation transmission mechanism having a speed reduction ratio of 1/integer number (inclusive of 1/1), and the exposure unit is provided with a recording start position control unit for starting recording image information from a predetermined reference position on the photosensitive drum.
