Abstract:
1. An image recording apparatus having an image holding material which is charged and rotated and is exposed by an exposing unit and on which an electrostatic latent image is formed, a developing unit which adheres toner onto said electrostatic latent image on said image holding material, a medium feeding unit which feeds out a recording medium, a conveying unit which is driven by a driving unit after a skew of said fed-out recording medium is corrected and which conveys said recording medium toward a transfer position, and a transfer unit which transfers said toner adhered on said image holding material onto said recording medium which is arranged at said transfer position and is conveyed, comprising: an exposure control unit which drives said exposing unit on the basis of said driving of said conveying unit; a medium detecting unit which is arranged between said conveying unit and said transfer position and outputs a detection signal when a front edge of said conveyed recording medium is detected; and a conveying speed control unit which measures a time which is required until said detection signal is received after said driving of said conveying unit is started, sets a conveying speed of said conveying unit in order to allow an exposure start position of said image holding material to coincide with a transfer start position of said recording medium at said transfer position on the basis of a time difference between said measured time and a set time, and controls said driving unit wherein:
