Abstract: An image forming apparatus configured to form an image on a transfer medium with a developer includes: an image bearing member on which an electrostatic latent image is formed, the developer is supplied to develop the electrostatic latent image, and an image to be transferred onto the transfer medium is formed, the image bearing member having surface hardness of 150 N/mm to 220 N/mm in a universal hardness value (HU); a developing device configured to supply the developer to the image bearing member; a cleaner configured to be brought into press-contact with the image bearing member at press-contact linear pressure x in a range of 16.7?x?22.0 [mN/mm]) and collect components of the developer remaining on the image bearing member after the image is transferred onto the transfer medium; and a lubricant containing fatty acid metal salt arranged at a distal end of the cleaner being in contact with the image bearing member, at an arrangement amount y in a range of 25?y?100 [ng/mm] to satisfy a condition y?12.

Abstract: Dust collection portions are installed at both ends of a holding plate installed on a shield plate of a charger. On the other hand, in a cleaning device, a dust collection member is installed so as to make contact with the shield plate and holding plate. Dust such as discharge products and toner occurred when moving the cleaning device and cleaning a sawtooth discharge electrode falls on the side of the charger where the holding plate of the shield plate is installed. The cleaning device, since the dust collection member is installed, cleans the sawtooth discharge electrode, simultaneously collects dust such as discharge products and toner on the shield plate by the dust collection member, and can collect dust in the dust collecting portions installed at both ends of the holding plate. By doing this, the grid can be prevented from adhering of dust and the print quality is prevented from lowering.

Abstract: A charger in one embodiment of this invention includes an electrode cleaning mechanism having a film-like elastic sheet which is deformed by a provided predetermined stress, wherein deposits deposited on the edge of a sawtooth electrode are removed, and a potential above a certain level can be given to the surface of a photoconductor drum.

Abstract: When there are sheets of paper in paper cassettes of a main body of an apparatus, symbols of a paper size display of an image forming apparatus graphic displayed on a touch panel are lit and indicated at clear density. On the other hand, when the paper cassettes are empty, the symbols of the paper size display blink or the density of the symbols is made lower or is turned off, thus a warning is displayed. By doing this, a user, only by looking at the image forming apparatus graphic, can easily recognize which paper cassette is empty.
