PROBLEM TO BE SOLVED: To reduce unnecessary toner consumption, while suppressing the occurrence of deterioration of image quality such as roughness of images due to deterioration of toner.SOLUTION: In performing inter-paper toner refreshing mode to perform toner forcible consumption control to forcibly consume a toner in a developing device, in a non-development processing period other than a development processing period during which latent images are subjected to development processing according to image information in a continuous image forming operation, when transfer bias of the continuous image forming operation is superimposed transfer bias, an image forming apparatus controls the amount of toner forcibly consumed in the inter-paper toner refreshing mode performed in the continuous image forming operation to be smaller than that in the case where the transfer bias in the continuous image forming operation is DC transfer bias. |
