Title: Imaging device and process cartridge
Inventor: MOTOHASHI SATORU
IPC: G03G21/00
Filed: 2001-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent image defects caused due to faulty charging by preventing soiling substance, such as toner from being excessively accumulated at the specified position of an charging roller. SOLUTION: A shaft center (p) of the charging roller 2 is arranged at a twist position with respect to the shaft center (q) of a photoreceptor drum 1, and a crossed axes angle θ (θ≠0 deg.) is in stalled between respective buses. When forming an image, the drum 1 is normally rotated, in a direction shown by an arrow R1 so as to submissively rotate the roller 2 in the direction shown by arrow K1. Thus, the roller 2 is moved in the direction shown by arrow A. Meanwhile, by making the drum 1 rotate in reverse a direction shown by arrow R2 with a specified timing at image non-forming time, the roller 2 is drivenly rotated in the direction shown by arrow K2. Thus, the roller 2 is moved in the direction shown by arrow B.  Since the roller 2 undergoes reciprocative movement in the directions shown by the arrows A and B, along the shaft center (p) by the normal rotation and by the reverse rotation of the drum 1 in this way, the soiling substances such as the toner hardly accumulate at the specified position of the roller 2.

IPC: G02B26/10
Filed: 2001-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain an optical deflector capable of realizing miniaturization, fast starting, a small loss and a low cost. SOLUTION: A driving coil 24 is mounted to a driving circuit substrate 26 through a driving circuit substrate 26 through a positioning member 28. Thus, a distance between the coil 24 and a driving magnet 30 is reduced. As the result of this, conventionally leaked magnetic flux B1 is used effectively. Consequently, without increasing magnetic fluxe density of magnetic fluxes B2 from the magnet 30 to the substrate 26, a rotator 20 can be started fast and driving efficiency can be improved. Since there is no need to increase the size of the magnet 30, a low cost is realized and the increase of the mass of the rotator 20 can be prevented with this, thereby the small loss is attained.
