    摘要： An image forming apparatus has a photosensitive drum, a charger for uniformly charging a surface of the drum, an optical head for irradiating the surface of the drum with light to change a charging state of the drum surface, and a developing device for causing a toner to adhere on the surface of the drum in accordance with the charging state. The charger has a grid with two wire fixing portions each provided with two grooves, a first discharge wire fitted in one of the two grooves of each wire fixing portion, and a second discharge wire fitted in the other of the two grooves of each wire fixing portion. The two grooves of each wire fixing portion are arranged relative to the grid so that the first and second discharge wires are arranged parallel to one another along a substantial center in a width direction of the grid.

    摘要： A pulse-like DC voltage is applied from two power sources to transfer residual toner uniformizing means and toner charge amount control means, respectively, to expel transfer residual toner deposited on these means from these means onto a photosensitive drum. In a low humidity environment, the number of application of the DC voltage is increased so as to sufficiently expel the transfer residual toner because the transfer residual toner is less liable to be expelled even when the pulse-like DC voltage is applied to the above two means in the low humidity environment in which an absolute moisture content in atmosphere is small and electrical resistances at portions of a photosensitive drum contacting the above two means.

    摘要翻译： 从两个电源施加脉冲状的直流电压以分别转移残留的调色剂均化装置和调色剂充电量控制装置，以将沉积在这些装置上的转印残余调色剂从这些装置排出到感光鼓上。 在低湿度环境下，由于转印残留调色剂即使在将脉冲状的直流电压施加到上述两个时也难以排出，所以直流电压的施加次数增加，从而充分地排出转印残留调色剂 意味着在低湿环境中，大气中的绝对含水量小，感光鼓部分接触上述两种方式的电阻。
