An image-forming apparatus including a cleaning means for selectively removing foreign matters other than developer remaining on the surface of a photoconductor drum therefrom after a transferring process. The cleaning means is provided with a foreign-matter removing roller which comes into contact with the surface of the photoconductor drum. Foreign matters, which are charged by a transferring device to have a polarity reversed to that of the charged electric potential of toner through an electric field that is exerted between the surfaces of the roller and the photoconductor drum, are allowed to adhere to the surface of the foreign-matter removing roller. As for the surface of the foreign-matter removing roller, the surface electric potential of the foreign-matter removing roller is biased farther toward the polarity of the charged toner than the surface electric potential of the photoconductor drum at the contact portion between the photoconductor drum and the foreign-matter removing roller. Thus, it becomes possible to provide an image forming apparatus which is capable of supplying images with good picture quality for a long time, by using a cleaning operation of this cleaning means.

An abnormality detection apparatus for a multi-cylinder internal combustion engine changes a fuel injection quantity of a predetermined target cylinder to detect an abnormality of an internal combustion engine based on values of rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity. The abnormality detection apparatus corrects the values of the rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity based on at least one of the number of revolutions of the engine and an engine load at a corresponding detection time.

An apparatus for detecting imbalance abnormality in an air-fuel ratio between cylinders in a multi-cylinder internal combustion engine according to the present invention increases a fuel injection quantity to a predetermined target cylinder to detect imbalance abnormality in an air-fuel ratio between cylinders at least based upon a rotation variation of the target cylinder after increasing the fuel injection quantity. The increase in the fuel injection quantity is carried out in the middle of performing the post-fuel-cut rich control. Since timing of the post-fuel cut rich control is used to increase the fuel injection quantity, the exhaust emission deterioration due to abnormality detection execution can be prevented as much as possible.
