    • An image forming apparatus includes: an image support medium; a charging member for charging the surface of the image support medium in contact with the surface of it; an exposure device for irradiating with light the surface of the image support medium charged by the charging member to form a static latent image; a developing device for supplying developer to the static latent image formed on the image support medium to develop the latent image and for removing the leftover developer on the image support medium; a transfer device for transferring the developer image, which has been developed on the image support medium by the developing device, to a member to be transferred; and a scraping member for scraping foreign matter such as dust and paper particles on the image support medium. The image forming apparatus is constructed such that the charging member causes the developer to adhere to the scraped foreign matter, and then the foreign matter is collected by the developing device through the image support medium. The scraping member is held by a holder which has an opening for allowing the foreign matter to pass through into the charging member housing.

    • The invention provides an efficient method for the preparation of cycloheone by the liquid-phase oxidation of cyclohexene in the presence of a catalyst system. The rate of conversion of the cyclohexene and the yield of cyclohexanone are unexpectedly increased when the reaction mixture brought into contact with oxygen or air contains a limited amount of an aliphatic alcohol having 2-10 carbon atoms in a molecule such as ethyl alcohol with the catalyst system composed of a palladium compound, e.g. PdCl.sub.2, and at least one co-catalytic ingredient which is a copper compound or iron compound such as CuCl.sub.2 or FeCl.sub.3. The influence of benzene or cyclohexane admixed in the reaction mixture was studied to indicate no adverse effects or even better results in the reaction giving further advantages of the process in which the starting cyclohexene need not be purified and can be used as prepared by the partial hydrogenation of benzene or partial dehydrogenation of cyclohexane.
