Description

[Brief explanation of the drawing]

Fig. 1 is a vertical sectional view of the developing unit set at a predetermined position within the copying machine main body, with the copying machine main body omitted and only the outline of the unit carrier shown. The figure is a schematic perspective view showing the unit carrier removed from the copying machine main body and the developing unit separated from the unit carrier.
FIG. 3 is a front view of the developing unit and unit carrier set at predetermined positions in the copying machine main body. In order to make the figure easier to understand, the copying machine main body and toner reinforcing device are omitted, and the developing unit and the toner reinforcing device are omitted. Figure 4 is a simplified view of the unit; Figure 4 is a front view similar to Figure 3 with the front plate of the unit carrier removed; Figure 5 is a plan view of the guide member fixed to the main body of the copying machine. Figures 6a and 6b, which show the guide groove and guide pin provided on the unit carrier side with chain lines, show the state in which the developing unit and unit carrier are set, and the state in which they are pulled out. FIGS. 7a, b, and c, which are schematic explanatory views of the state seen from the left side of FIG. 1 to explain the operation, are similar to FIG. 6 when the developing unit and unit carrier are pulled out from the set state. Figure 1 is a schematic explanatory view from above, showing how the developing unit rotates and the photoconductor drum FIG. 10 is a simplified explanatory diagram with some elements omitted, showing the situation when the developing unit is separated from the copying machine. FIG. FIG. 1 is a cross-sectional view showing a state in which the device is supported on a floor surface or the like, with some elements omitted and simplified as in FIG. 9;
Figure 1 is a side view showing the same state as Figure 10, with some parts omitted and simplified, and Figures 12a and b show the stand device in its folded state and in its used state. Fig. 13 is a plan view showing the drive system of the developing unit, with some elements omitted, and Fig. 14 shows the idle gear engaged with the gear of the developing unit. FIG. 15 is an explanatory diagram illustrating the state in which the idle gear is disengaged from the gear of the developing unit. 1... Developing unit, 4, 4R, 4B... Developer chamber, 9, 9R, 9B...

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a developing device of an image forming apparatus that visualizes an electrostatic latent image formed on a latent image carrier, the developer discharged from the developer chamber of the developing device is The developing device is characterized in that it is provided with a removable developer case for receiving and collecting developer. (2) A utility model in which the developing device includes a developing unit that visualizes an electrostatic latent image and a unit carrier that supports the unit, and the case is detachably attached to the unit carrier. A developing device according to claim 1. (3) Utility model registration claim 2, wherein the unit carrier is supported by the main body of the image forming apparatus so as to be able to be pulled out together with the developing unit.
Developing device described in section. (4) The developing device according to claim 2 or 3, wherein the unit carrier is supported by the main body of the image forming apparatus so as to be detachable from the main body while supporting the developing unit.
