ABSTRACT:
An image forming apparatus for forming a toner image on a recording medium. The apparatus includes a photosensitive drum on which a latent image is formed, a developing/cleaning device for developing the latent image with a developing agent and for removing the developing agent remaining on the photosensitive drum therefrom while the latent image is developed, and a transfer device for transferring the developed image on the photosensitive drum to the sheet. The apparatus further includes a disordering device for disordering the developing agent remaining on the photosensitive drum, after transfer of the developed image by the transferring means, to render the developed image nonpatterned. The disordering device includes a contact member having projections and depressions formed with a prescribed inclined angle relative to the direction intersecting at right angles the rotating direction of the photosensitive drum at the contact portion with the photosensitive drum.
