Abstract

A gear arrangement for a development unit of an imaging device employing an electrophotographic process. The development unit is provided with a rotation member and swingably supported by the main body of the imaging device through a support shaft to be mounted on a predetermined position of the main body of the imaging device. An input gear is provided on the development unit and coupled with the rotation member thereof to be meshed with a drive gear provided with the imaging device. The rotational force of the drive gear is transmitted to the input gear to thereby rotate the rotation member. The drive gear and the input gear are disposed such that a line obtained by extending a line of action as a moving locus of the point at which the tooth of the drive gear is in contact with the tooth of the input gear is substantially directed to the direction of the support shaft through which the development unit is supported by the main body of the imaging device.
