Abstract:
1. An image carrier comprising: a support that circulatively rotates, a plurality of pixel electrodes that are provided on the support and placed like a matrix for each pixel unit along a rotation direction and a rotation axis direction of the support so as to form a latent image based on an image signal, the plurality of pixel electrodes further arranged in a center circumferential area of the support, and arranged with a circumferential area on each side of the center area in which no pixel electrodes are placed, wherein the matrix-like placement of the pixel electrodes uniformly covers the entire center circumferential area; a plurality of switches that are placed like a matrix on the support in a one-to-one correspondence with the pixel electrodes for switching a supply timing of a latent image forming signal so as to form a latent image based on the image signal for the pixel electrodes; a plurality of scan signal lines that are provided on the support so as to extend along the rotation axis direction of the support for transmitting a scan signal for selecting and scanning in sequence the supply timing of the latent image forming signal to a group of the plurality of switches corresponding to the pixel electrodes arranged in a row along the rotation axis direction of the support; a plurality of latent image forming signal lines that are provided on the support so as to extend in the rotation direction of the support for transmitting the latent image forming signal to a group of the plurality of switches corresponding to the pixel electrodes arranged in a row along the rotation direction of the support; a plurality of signal leads that are provided on the support so as to extend in the rotation axis direction of the support and connected to the latent image forming signal lines for drawing out the latent image forming signal line toward an end part other than a pixel electrode placement area in the rotation axis direction on the support; a scan signal supply device that are provided in an end part other than the pixel electrode placement area in the rotation axis direction on the support or any other part passing through the end part and connected to the plurality of scan signal lines arranged in the rotation direction of the support for supplying a scan signal to each scan signal line; and a latent image forming signal supply device that are provided in an end part other than the pixel electrode placement area in the rotation axis direction on the support or any other part passing through the end part and connected to the plurality of signal leads arranged in the rotation direction of the support for supplying the latent image forming signal to each signal lead.
