Abstract:
An image forming apparatus  100  in which a charging process of a photosensitive member  1  is performed by forming a combined surface potential Vd(U+L) by superimposing, on a first charge potential Vd(U) formed on a surface of the photosensitive member  1  by a first corona charger  31,  a second charge potential Vd(L) provided by the second corona charger  32  has a constitution including a control means  200  for executing an adjusting operation in which a superimposition start voltage Vg(L)A which is the second voltage Vg(L) at which formation of the combined surface potential Vd(U+L) is started is acquired by changing the second voltage Vg(L) applied to a grid electrode of the second corona charger in a state that the first charge potential Vd(U) is formed on the surface of said photosensitive member  1  and in which setting of the second voltage Vg(L) during the charging process is adjusted on the basis of the superimposition start voltage Vg(L).

Claim (Index 9):
An image forming apparatus according to  claim 8 , wherein said control means sets the second voltage Vg(L) during the charging process so as to satisfy the following formula:\n 50( V )\u2264|Vg( L )|\u2212|Vg( L ) A|\u2264 250 ( V ).
