摘要: A color electrophotographic apparatus eliminates necessity of mechanism for urging the developer from the front side. The developer is placed away from a photo conductor. On both sides of the developer, mutually cooperated gears are provided. One of the gear meshes with a drive gear with a clutch for driving the developer. The other gear is meshed with a brake gear coupled with a brake mechanism whose brake function can be turned On and OFF by an electric signal. The drive gear is arranged to urge the developer onto the photo conductor by rotation thereof. When the gear of the developer rotates, the brake gear is arranged at a position to urge the developer onto the photo conductor. The torque to start slippage of the brake is set at a value to be greater than a force of a spring pushing back the developer.

摘要: An alignment apparatus for use in an electrophotographic imaging device includes a first counter to count a first value of changes of a first signal, with the first value related to a first location of a photoconductor in a first direction. In addition, the alignment apparatus includes a second counter to count a second value of changes of a second signal, with the second value related to a second location of the photoconductor in a second direction substantially perpendicular to the first direction. Additionally, the alignment apparatus includes a circuit coupled to the first and the second counter to generate a change in a third signal after the first and the second counter count to, respectively, the first value and the second value.
