Title:
IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2002278362
Kind Code:
A
Abstract:

To provide an image forming device capable of stably rotating an image carrier and reducing its size.

A copying machine provided with a photoreceptor 1, a charging device 3 for uniformly charging the surface of the photoreceptor 1, an exposure device for forming an electrostatic latent image by irradiating the photoreceptor 1 with light, a developing device 5 for developing the electrostatic latent image as a visual image on the basis of the gradation information of picture data, a transfer roller 8 for transferring the visual image of the photoreceptor 1 to transfer paper, a rotational shaft 2 connected to the photoreceptor 1, a driving motor 33 for driving the rotation of the shaft 2, and a transmitter 51 for transmitting driving force from the motor 33 to the shaft 2, is provided also with a magnet 28a to be rotated at a rotational angular speed different from that of the shaft 2 to induce the torque of the photoreceptor 1 by the magnet 28a.
