PURPOSE:To facilitate removal of parts out of order and to prevent effect of an unevenly loaded developer by driving only a developing device for a prescribed time before driving an image forming device divided into 2 components of upper and lower machine parts. CONSTITUTION:An upper machine body 1 provided with a photosensitive body 3, a developing device 4, etc. and a lower machine body 2 provided with a conveying device and a fixing device 6 are combined with a hinge 7. Since the body 1 can be released open, inspection of the devices and exchange of parts out of order are made easy, but the release of the body 1 inclines the developing device 4 and localizes the developer one-sidedly. Since only the developing device 4 is driven for a prescribed time before the start of the photosensitive body 3 by the signal of a sensor 8 when the body 1 is closed, the one-sided localization of the developer can be corrected. |
