Abstract:
1. An image forming apparatus, comprising: a carriage mechanism configured to support a light source and at least one mirror in a way to be movable at a predetermined speed; a motor configured to move the carriage mechanism; a motor drive mechanism configured to supply a motor driving current to the motor; condition detecting mechanism configured to detect conditions for variation of the magnitude of the motor driving current under a predetermined condition; a charge-coupled device (CCD) sensor configured to convert, into image data, light which is reflected from a reading object illuminated with light coming from the light source; an exposure light device configured to output light whose intensity varies responsive to the image data obtained from the CCD sensor; an image carrier configured to allow a latent image to be formed thereon with the light from the light exposure device; a developing device configured to supply a toner to the latent image on the image carrier to make the latent image visible; a fixing device configured to fix that visible image to a to-be-fixed materials, a temperature sensor configured to detect a temperature of the fixing device; and a motor driving current controller configured to control the motor driving current to increase the motor driving current at a predetermined rate when the temperature of the fixing device which is detected by the temperature sensor is lower than a predetermined temperature.
