Abstract

An object of the present invention is to provide a recording head which is constructed as a line head by arranging a plurality of head components along the direction of arrangement of recording elements and in which an amount of a gap of the recording elements at each of the joints between each pair of the head components located adjacent to each other along the direction of arrangement of the recording elements is detected to achieve recording of a high-quality image free from a stripe shape nonuniformity, a blank defect, a color nonuniformity, and the like. To achieve this object, the recording head has a head portion for recording an image on a recording medium, and a sensor portion for reading the image recorded on the recording medium by the head portion. In the head portion, a plurality of head components each formed by arranging recording elements for recording an image on the recording medium are arranged along the direction of arrangement of the recording elements. In the sensor portion, a plurality of reading elements for reading the image recorded on the recording medium are arranged in one direction. The head portion and the sensor portion are placed on one base member while being fixedly positioned relatively to integrally form a head module.
