摘要： PROBLEM TO BE SOLVED: To provide an image carrier driving unit and an image forming apparatus which facilitate assembly of driving parts and angle adjustment and suppress color shifting and density unevenness. SOLUTION: To configure a photoreceptor driving unit 10 so as to be attachable/detachable to/from a body frame 2 of the image forming apparatus 1. The photoreceptor driving unit 10 includes a row of photoreceptor drives such as a photoreceptor driving gear for driving the photoreceptor arranged between two side plates. In this embodiment, a row of developing drives for driving the developing unit is also arranged in the unit 10. Adjustment after assembling to the body is not necessary since the photoreceptor driving unit 10 has adjustment such as positional accuracy, angle accuracy or phase matching in the row of photoreceptor drives carried out in the unit state. Furthermore, a row of developing drives is arranged by effectively using the space in the unit. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing effect of variation in rotational speed of a transfer driving roller even when a diameter of a driving roller and a diameter of an image carrier are approximately the same and adjusting a difference in phase between image carriers at good precision. SOLUTION: The image forming apparatus creates a reference pattern group for each color for a length which is the least common multiple of periphery length of the transfer driving roller 45 and periphery length of a photoreceptor 2, and measures detection time between the reference pattern images. Periodical variation in the transfer driving roller 45 can be effectively eliminated without forming the reference pattern to be needlessly long by an averaging process of measured data corresponding to a position of the photoreceptor 2 among the measured data.

摘要： PROBLEM TO BE SOLVED: To allow supply of power to the power receiving roller of an intermediate transfer unit in a position where it can be visually checked and to facilitate checking and fixing of troubles, for instance, bending of a connection terminal.
SOLUTION: A power supply member 73 which supplies power from a high voltage power source 51 disposed in the main body of an apparatus to a conductive bearing 71 attached to the end of the power receiving roller 18 of the intermediate transfer unit disposed in the main body of the apparatus is accommodated in the main body 55a of a power supply face plate 53 which can be rotated to the position where the opening of the main body of the apparatus is opened or closed. This makes it unnecessary for electric wiring for the supply of power from the high voltage power source 51 to the power receiving roller 18 to be disposed in the main body of the apparatus. In addition, the connection terminal 52 of the high voltage power source 51 and the bearing 71 serving as the power receiving portion of the power receiving roller 18 can be disposed on the opening side. Accordingly, if a connection terminal 52 or a bearing 71 has troubles of bending or the like, the checking of them or fixing of the troubles can speedily be performed.
