<P>PROBLEM TO BE SOLVED: To solve the following problem of an image forming device adapted to high toner charge amount: density change with respect to the change in image forming environment cannot be properly adjusted by adjusting developing bias, and desired image density cannot be obtained. <P>SOLUTION: The image forming device uses carrier configured to prevent resistivity from being linearly changed with respect to electric field intensity, to control the electric field intensity to be applied to the carrier. <P>COPYRIGHT: (C)2013,JPO&INPIT |
