摘要： There is disclosed a rotary polygon mirror capable of precise light beam scanning operation with a uniform amount of light. The mirror is composed of aluminum or aluminum alloy, and an aluminum oxide protective film is formed on the reflecting faces. The optical thickness of the aluminum oxide film is within a specified range, in order to reduce the variation in reflectance resulting from variation in incident angle of light or from eventual fluctuation in the film thickness. The aluminum oxide film can be formed in various methods, for example CVD.

摘要： PROBLEM TO BE SOLVED: To provide a corona discharge device that reduces excessive amount of charge wire 106 to be taken up even after repeated take-up operation of the charge wire 106.SOLUTION: A corona discharge device includes a take-up control part 105 that counts the accumulated rotation amount of a take-up reel 110, and controls a take-up motor 107 so that the rotation amount of the take-up reel 110 is decreased relative to a unit take-up length of a charge wire 106 as the accumulated rotation amount of the take-up reel 110 increases. Accordingly, quantitative take-up of the charge wire 106 can be carried out even though the apparent reel diameter of the take-up reel 110 is increased as the take-up operation is repeated.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of long term use of a driving motor which drives a cleaning member of a charging wire of an electrifier. SOLUTION: The image forming apparatus 100 includes a configuration in which the electrifier 1 is removed independently of the driving device 2 from an apparatus body 50 of the image forming apparatus. The driving device includes: a motor support member 104 which rockably supports a driving motor 110 such that the driving motor is brought into and out of contact with a spiral shaft 120; a first biasing member 105 for making the motor support member rock and biasing the driving motor toward the spiral shaft; and a second biasing member 103. When the electrifier is fixed at a predetermined position in the apparatus body, the second biasing member regulates a position in the longitudinal direction of the electrifier by pressing a pressing part 101a, provided in the electrifier, against the motor support member. When the electrifier is removed from the apparatus body, the second biasing member holds the driving motor at a position separated from the spiral shaft and also biases the electrifier in the removing direction from the apparatus body.
