摘要： An image forming apparatus includes an image holding member for forming a toner image, and a transfer roller for transferring the toner image formed on the image holding member onto a recording paper sheet. The absolute value of (.DELTA. log R)/.DELTA.V[(log .OMEGA.)/kV] representing the voltage dependence of resistance R of the transfer roller is set not more than 0.5. The contacting portion of the transfer roller and an intermediate belt can be uniformly discharged, and therefore intermediate belt can be prevented from being changed in its property. As a result, an image forming apparatus having a stable transfer characteristic can be provided.

摘要： A printer detects density of a toner pattern on an intermediate transfer belt, operates a differential value for the detection value, and compares the differential value with a threshold value. If fluctuation of detection values is great and there are detection values of which differential values exceed the threshold value, those detection values are assumed to contain noise due to abnormality of the shape on the belt, and the detection values in such a range are corrected using curve approximation. A tone correction table is updated using the corrected detection values.
