  • Patent number: 8699079
    Abstract: An image forming apparatus is provided which realizes an adequate operation of a paper dust removing device. The image forming apparatus has a storing portion which stores the likelihood that paper dust is produced upon previous image formation as previous paper dust production information according to the type of sheet. Further, the image forming apparatus has a CPU which adjusts paper dust removing performance upon current image formation to increase based on previous paper dust production information when the likelihood that paper dust is produced upon previous image formation is higher. Consequently, it is possible to realize an adequate paper dust removing operation of the paper dust removing device and prevent problems of images from occurring due to paper dust.
