Abstract
A recording apparatus builds an image at high quality without occurrence of malfunctions attributable to raised/recessed spots on the surface of a conveyance belt and insufficient dimensioning for the width of the conveyance belt, while preventing the interior of the recording apparatus from being contaminated with erroneously ejected ink. The recording apparatus includes a conveyance belt for conveying a recording sheet below four kinds of recording heads, and the conveyance belt has a joint line along which the opposite ends of a band-shaped material are joined to each other. In addition, the conveyance belt has a band-shaped colored portion which is located remote from the joint line by a predetermined distance. The colored portion is detected by an optical sensor, and a control unit controls the driving of the conveyance belt in response to a signal derived from the detection of the optical sensor.
