摘要： In an electrophotographic image forming apparatus employing a contact development system, contact of a development roller 64 against a photosensitive drum 61 is started while forming an electrostatic latent image of a detection pattern 81 for detection in each individual apparatus, and a developed toner image is detected at a predetermined position. At this time, a time as from the time when contact of the development roller 64 was started until the time when the toner image was detected is measured, and a delay time Xs from a time (t11) when contact operation of the development roller 64 was started until a time (t131) of actual contact is calculated by subtracting the time needed until the developed toner image reaches the detection position. The time when contact of the development roller 64 is started is delayed by this time. The same sort of control is also performed for the separation time.

摘要： A second mode to form an image is based on a predesignated type of recording medium, whereas a first mode to form an image is based on the detected type when a detection is performed to a recording medium which is fed.
To provide for optimal image forming conditions and throughput, in case, a detection is performed to a recording medium which is fed in the second mode whereas, in the first mode, image forming conditions are set based on a former result of the sheet type detection without executing the sheet type detection anew.
