摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus made more inexpensive and achieving accurate image reading and improvement of throughput, and to provide its control method. SOLUTION: While recording paper conveyed the first in consecutive printing is temporarily stopped, its surface property is read by an image reading sensor 40, so that the kind of the first paper is discriminated. The image forming condition of an image forming part is set in accordance with the result of discrimination. While the second and succeeding sheets of recording paper are conveyed, the surface property is read by the sensor 40 so as to decide whether the kind of the second and succeeding sheets of paper is the same as that of the first sheet of paper. When they are the same, the image is formed by applying the image forming condition for the first recording paper to all the recording paper. When they are not the same, the image forming condition for the first recording paper is applied to the first sheet of recording paper but not applied to the second and succeeding sheets of paper.
