Abstract
A driving device, an image forming device, and an image forming apparatus are disclosed. In at least one embodiment, the image forming device includes a first rotator and a second rotator, which are arranged in parallel with each other. The driving device rotates the first rotator with a rotational speed different from a rotational speed of the second rotator.
Claims20
A driving device for driving first rotating means for rotating asynchronously with a photoconductor of an image forming apparatus, the driving device comprising:
- first generating means for generating a drive force by rotating at a first input rotational speed;
- and
- first transmitting means for transmitting the drive force from the first generating means to the first rotating means to drive the first rotating means at a first output rotational speed converted from the first input rotational speed, the first output rotational speed being different from a second output rotational speed of second rotating means arranged in parallel with the first rotating means.
An image forming device, comprising:
- a photoconductor configured to be rotatably driven by a photoconductor driving device;
- a first rotator, provided in a vicinity of the photoconductor, configured to be rotatably driven by a first rotator driving device at a first rotational speed;
- and
- a second rotator, provided in a vicinity of the photoconductor, configured to be rotatably driven by a second rotator driving device at a second rotational speed, the second rotational speed being different from the first rotational speed.
