Title: Developing device and image forming device using the same
Inventor: YOSHIZAWA HIDEO
IPC: G03G15/08
Filed: 1993-04-17
Abstract: PURPOSE:To obtain a satisfactorily developed image even when the device is used in a place that slopes in the axial direction of a developer carrier. CONSTITUTION:The lower case 3b of a developing unit 3 is fixed to its upper case 3a via a shrinkable base material 4. When the level of developer in the developing unit 3 is inclined because the unit is set in a place that slopes in the axial direction of the developing roller 6, the lower case 3b on the side of the higher level is pushed up. Consequently, developer on the side where the lower case 3b is pushed up is also pushed up, and the level of the developer reservoir in the developing unit 3 rises. Thus, since a paddle 7 is sufficiently buried in the developer even on the side that has risen due to the inclination, a sufficient mount of developer can be carried and supplied to the developing roller 6.

Abstract: PURPOSE:To omit artificial switch setting operation and to elminate erroneous setting of a switch by adding a special code. CONSTITUTION:Necessary read-only memory element is mounted on a printed substrate of a system that uses a read-only memory element and energizing is started. Basing on a code 1A that confirms mounting of special code 1 added to the read-only memory element, in the case where the read-only memory element is mounted, judgement is made as to whether the place of mounting is to be designated or not basing on a function defining code 1B, and then judgement is made as to whether the place of mounting designated by a place of mounting designating code 1C concides or not with the place where the read-only memory element actually mounted. As a special code is added to the read-only memory element, it is not necessary to provide a device discriminating switch, and separate defining of operation function becomes possible.
