PURPOSE:To always obtain a stable output image by properly performing the dynamic correction corresponding to the change of properties of the photoreceptor. CONSTITUTION:The photoreceptor 1, forming the area divided into plural numbers allowing to be specified by the coordinates on the surface, is provided with the temporary storage means for temporally storing the physical quantity in the process executed corresponding to the photoreceptor 1 by the image forming means with regard to one or plural process out of the electrification, the exposure, the development and the transfer process or the state value consisting of some index value basing on the physical quantity by the respective area, then provided with the comparison means for comparing the state value temporally stored in the temporary storage means and the photoreceptor property value preliminarily stored in the storage means for each area, and moreover provided with the image forming condition control means for correcting at least one element out of the electrification quantity, the exposure quantity, the development quantity and the transfer quantity basing on the comparison result. |
