Abstract:
1. An image forming apparatus comprising: a paper feeding mechanism that feeds paper piece by piece; a paper conveying path that conveys paper fed by such paper feeding mechanism to a paper discharging unit; an image forming unit situated on the paper conveying path between the paper feeding mechanism and the paper discharging unit on such paper conveying path to execute an image forming process for forming an image based on image data and to print the image on the paper being conveyed on the paper conveying path; a sensor that is situated on an upstream side of the paper conveying path with respect to the image forming unit to detect a type of paper conveyed by such paper conveying path; a condition setting unit configured to set conditions for an image forming process of the image forming unit in accordance with a detection result of such sensor; an image-forming-process control unit that is situated to start the image forming process of the image forming unit waiting until conditions for an image forming process of the image forming unit are set in accordance with a detection result by the sensor when a paper fed to the paper conveying path by the paper feeding mechanism was not detected by the sensor, and that is situated to start the image forming process without awaiting paper type detection when a paper fed to the paper conveying path is fed from the paper feeding mechanism and a type of paper from the paper feeding mechanism was detected by the sensor; and a paper-conveying-path control unit configured to cause the paper conveying path to convey paper conveyed by the paper conveying path to the image forming unit, in which the image forming process is started, in synchronization with a printing operation of the image forming unit.
