Abstract:
1. An image forming apparatus comprising: a paper feeding mechanism that feeds paper piece by piece; a paper conveying path that conveys, when paper is fed by this paper feeding mechanism, this paper to a paper discharging unit; an image forming unit configured to be arranged between the paper feeding mechanism and the paper discharging unit on this paper conveying path and execute an image forming process for printing an image based on image data on the paper being conveyed by the paper conveying path; a sensor that is arranged on an upstream side with respect to the image forming unit on the paper conveying path and detects a type of paper conveyed by this 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 value detected by this sensor; an image-forming-process control unit configured to not start the image forming process when paper fed to the paper conveying path by the paper feeding mechanism is the paper not detected by the sensor and start the image forming process without awaiting paper type detection when paper fed to the paper conveying path is detected by the sensor; and a paper-conveying-path control unit configured to cause, when paper fed to the paper conveying path is the paper not detected by the sensor, the paper conveying path to discharge the paper through the image forming unit, in which the image forming process is not started, and cause, when paper fed to the paper conveying path is paper of a type same as paper detected by the sensor, the paper conveying path to convey the paper to the image forming unit, in which the image forming process is started, in synchronization with a printing operation of the image forming unit.
