摘要： An image forming apparatus includes an image bearing member, a charging roller and a pair of gap forming members. The image bearing member has a photoconductive surface including an image forming area for bearing an electrostatic latent image. The charging roller has a circular cross section with a first radius and a metallic core having a rotational axis of the charging roller, in parallel with and close to the image bearing member, and a charging surface for charging the photoconductive surface. The pair of gap forming members form a gap at least between the image forming area and the charging surface. Each of the pair of gap forming members have a circular cross section with a second radius such that a ratio of the second radius to the first radius is substantially constant through a whole rotational phase of the charging roller.

摘要： A charging unit is disclosed capable of reducing undue variation and fluctuation margin of a charging gap, and controlling accurately the proper gap durably over the change of environmental conditions, which is suitably incorporated into an image forming apparatus. The charging unit is configured to charge an image bearing member in a non-contact arrangement, including a charging roller provided with a core shaft, a charging member formed of electroconductive resin integrally disposed on the periphery of the core shaft, and gap holding members formed of insulating resin each disposed at respective ends of the charging member outside an image forming region. The control of the charging gap is feasible by either forming the gap with a charging member having such a materials condition as to satisfy the relation, |G30−G10|×5

摘要： In an electrophotographic image forming apparatus, a photoconductive element includes a photoconductive film having a thickness of 15 .mu.m or below. A light beam having a diameter of 50 .mu.m or below optically forms a latent image on the photoconductive element. Toner is caused to deposit on a dot image in an amount 1.2 times greater than on an area image. This is successful to minimize the variation of image quality and to render dots inconspicuous. The method of forming toner images is also included.
