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： An electrostatic latent image developing device equipped with a developing housing, a developing roller rotatably disposed between the two side walls of the developing housing, and a feeding roller rotatably disposed between the two side walls of the developing housing neighboring the developing roller. A first bearing member is mounted on one side wall and has two bearings for supporting the ends of the rotary shafts of the developing roller and the feeding roller. A second bearing member is mounted on the other side wall and has a bearing for supporting the opposite end of either the rotary shaft of the developing roller or the feeding roller. A third bearing member is mounted on the other side wall and has a bearing for bearing support of the opposite end of the rotary shaft of the developing roller or the feeding roller not supported in bearing fashion by the second bearing member. The second bearing member and the third bearing member are provided with a positioning device for defining a relative positional relationship between the second and third bearing members.

摘要： A DC/DC converter capable of preventing abnormal temperature increase in a power transistor. The DC/DC converter comprises a loop circuit, a power transistor, an abnormal high temperature detection circuit, and an abnormality processing circuit. The power transistor supplies an electric current to the loop circuit according to a control pulse signal. The loop circuit accumulates electromagnetic energy in an inductor when the electric current is supplied and generates a negative DC voltage by causing a loop electric current to flow by using the electromagnetic energy accumulated in the inductor when no electric current is supplied. The abnormal high temperature detection circuit detects a normal/abnormal state of temperature of the power transistor. The abnormality processing circuit switches the power transistor off when the abnormal high temperature detection circuit has detected that the temperature of the power transistor is abnormal.
