摘要： A gear assembly comprises at least two gears, each of which is formed by injection molding and has a plurality of ribs on their bases. The two gears have a gear ratio of 1:N and a ratio of the number of ribs is 1:M (N and M are integers). Alternatively, the two gears are supported in positions where one of ribs on one gear and one of ribs on the other gear lie on the same line at a predetermined number of times while one of gears rotates once. The two gears can also be supported in positions where the ribs on the two gears have predetermined positional relationships so that the two gears rotate at a constant angular speed.

摘要： An image forming apparatus includes a transfer belt device which transfers a toner image formed on a rotating photosensitive drum onto a recording sheet by providing corona charging from a rear surface of a transferring/conveying belt that is stretched around a driving roller and a driven roller, which conveys the recording sheet. A movable frame supports both ends of the rotational shafts of the driving roller and the driven roller. The movable frame is rotatably supported by a stationary housing of the transfer belt device. The movable frame can oscillate around a bearing section so that both ends of the rotational shaft of the driving roller connected with a driving source are supported. One end of the shaft of the driving roller connected with the driving source is supported by a stationary bearing member of the stationary housing. The other end of the shaft of the driving roller is supported by a movable bearing member which is movably provided in the stationary housing.
