Abstract
There is disclosed an image recording apparatus in which an image is read with an image sensor such as CCD and is supplied to light emitting diodes as recording elements for recording on an electrophotographic drum. The image data from the image sensor are stored in plural memories in parallel manner. A control circuit is provided for controlling the drive signals applied to each of the diodes, to drive such diodes a plural number of times in accordance with image signals applied thereto.

An image recording apparatus comprising:
- recording means including a plurality of light emission diodes arranged in a line, wherein each diode emits light in parallel with a junction face thereof;
- shift means for shifting a recording medium vertically to the line direction;
- drive means for driving each of said plurality of light emission diodes, respectively, on the basis of input image data;
- and
- control means for controlling said drive means to drive each said light emission diode in a line plural times with the same respective image data while shifting the recording medium so that the same line image data is recorded plural times by the light emission diodes in a line on the shifted positions, in recording medium.
