Abstract
An image forming apparatus includes an image forming means, for forming an image on an image receiver member, which in turn includes an image bearing member on which a toner image can be born, a latent image forming means for forming a latent image modulated by an electric signal on the image bearing member, and transfer means for transferring the toner image onto the image receiver sheet. Also included in the image forming apparatus are first detection means for detecting the density of the toner image on the image bearing member before an image transferring operation, second detection means for detecting the density of the toner image on the image receiver member after the image transferring operation, and control means for controlling a transferring condition of the transfer means and an image forming condition of the latent image forming means on the basis of detection results from the first and second detection means.
