Abstract:
An image forming unit is provided with a regulating member placed in such a way as to surround a charging roller to regulate movement thereof. The regulating member has a pressing section inclined with respect to a straight line connecting the center of the charging roller to the axis of the photoconductor, as seen from the axial direction of the photoconductor. The pressing section is inclined farther away from the photoconductor toward upstream of rotation of the photoconductor. The regulating member allows the charging roller to electrically charge the photoconductor with a simplified structure and prevents adhering substances from accumulating on the contact portion between the photoconductor and the charging roller.
