PROBLEM TO BE SOLVED: To prevent the curling or performance deterioration of a tonner cleaning member while avoiding the deterioration of print productivity or the blockage of the lifetime of components as much as possible in an electrophotographic image forming apparatus.SOLUTION: An image forming apparatus includes: an image carrier 11; charging means 12; latent image forming means 20; developing means 13; an intermediate transfer body 31; transfer means 32; first cleaning means 14 for cleaning toner remaining on the image carrier 11; second cleaning means 33 for cleaning the toner remaining on the intermediate transfer body 31; state detection means for detecting the state of the image forming apparatus; and control means 70. The control means 70 changes either a print start timing of a bias voltage of the developing means 13 in an image formation start sequence or a print stop timing of a bias voltage of the developing means 13 in an image formation end sequence on the basis of the detection result of the state detection means such that the toner is applied to the image carrier 11 and/or the intermediate transfer body 31.SELECTED DRAWING: Figure 1 |
