摘要： In an image forming apparatus having a photoconductive member supported via two supporting members fixed on a rotation axis and a flywheel with great moment of inertia, the characteristic oscillation frequency of the revolution system comprising the rotation axis, supporting members and photoconductive member is set so that any density unevenness on a toner image which is formed on the photoconductive member is not apparent even if an exciting torque affects the photoconductive drum. The moment of inertia of a rotation axis, a photoconductive drum, and a flywheel, a torsional regidity of the rotation axis and a mounting position of a support member, and a surface speed of the photoconductive drum all satisfy a specific relationship.

摘要： An image forming apparatus includes an intermediate transfer member which moves in one direction with a surface thereof facing and contacting an image carrier so as to transfer toner images for multiple colors from the image carrier to the intermediate transfer member to form at least one toner image page having the multiple colors superimposed thereon. An image transfer device transfers the toner image page on the intermediate transfer member to a recording medium or sheet, and a cleaning device, which is movable into contact with or away from the intermediate transfer member at predefined times, cleans the intermediate transfer member. The cleaning device is positioned so that a distance from an intermediate transfer nip portion entrance part to the cleaning device in the moving direction of the intermediate transfer member is greater than a length of the intermediate transfer member occupied by one or more toner image pages and a distance from the intermediate transfer nip entrance part to an intermediate transfer nip exit part.
