摘要： A process unit comprising a photoconductor unit and a developing unit supported pivotably via a support shaft. The photoconductor unit and the developing unit each have a pair of support side walls having support holes formed on the same axis. One pair of the support side walls define a pair of inner support side walls having an outside width smaller than the inside width of the other pair of the support side walls, while the other pair of the support side walls define a pair of outer support side walls. The pair of outer support side walls and the pair of inner support side walls are supported via the support shaft passing through the respective support holes. One end of the support shaft is supported by one of the outer support side walls via a bearing member detachably mounted in the support hole of the one of the outer support side walls.

摘要： A transferring device in which a transfer roller having a diameter which is not less than 60% of the diameter of an organic photosensitive drum with a diameter of 10 to 20 mm is arranged with a clearance provided between the transfer roller and the organic photosensitive drum. The transferring device avoids problems such as current leakage and reverse transfer of toner in the case of miniaturization of an image forming apparatus or contamination of the transfer roller, and easily sets a transfer current because an effective transfer current width is large.
