ABSTRACT:
A moving body moves in reciprocation in directions perpendicular to a feeding direction of a chart. An image carrier is mounted on the moving body and rotates in synchronism with a movement of the moving body. A charging unit is mounted on the moving body and changes the image carrier. A developing unit is mounted on the moving body and develops an electrostatic latent image formed by irradiating the image carrier charged by the charging unit with the light. A voltage dividing unit moving in synchronism with the moving body divides a predetermined voltage and supplies the divided voltages to at least the charging unit and the developing unit. An electric charge supplying unit may be used to supply electric charges to a holding unit for holding the electric charges under various conditions of the moving body.
