摘要： A transfer device that transfers color visual images of different colors from image carriers to each of first and second sides of a recording medium. The transfer device includes a transfer element that holds and moves the recording medium, transfer bias applying devices that apply transfer biases to the recording medium by the transfer element to transfer the color visual images from the image carriers to the recording medium, respectively, and an adsorbing bias applying device that applies an adsorbing bias to the recording medium to adsorb the recording medium to the transfer element. A polarity of the adsorbing bias applied to the second side of the recording medium is opposite to that of electric charge given to the recording medium due to electric discharge generated when the recording medium is separated from the image carriers after passing through transfer nip parts formed between the image carriers and the transfer bias applying devices.

摘要： An image forming apparatus includes a control device that calculates a developing ability of the developing device based on a detection value detected by an optical detection device from the plural toner patches. The control device adjusts an image formation condition based on the calculated developing ability. A factor detection device is provided to detect a contributing factor that causes the developing ability to largely change after the last adjustment of the image formation condition. The control device controls image formation such that when the factor detection device does not detect the contribution factor and a developing ability calculated this time is different from that calculated last time (as to a part of the plural toner patches), the plural toner patches are formed based on a prescribed fixed image formation condition so that an attraction amount of toner attracting to the plural toner patches enter a prescribed range detectable for the optical detection device. The remaining toner patches are formed (based on an image formation condition determined) in accordance with the image formation condition previously adjusted. When the detection device detects the contribution factor, the entire toner patches are formed based on the prescribed fixed condition.
