Filed: 1991-12-28
Abstract: PURPOSE:To obtain the field intensity distribution of a magnet with which to secure a coil charge timing without deteriorating the oscillation characteristics of a motor having a magnet and a coil arranged to receive its magnetic field. CONSTITUTION:A magnetization is applied so that the field intensity distribution curvature of a magnet 16 is to be formed by the fundamental wave and the third harmonic component. Thus, it becomes possible to output an induced voltage waveform capable of detecting the rotational position of a rotor, and at the same time, to reduce the noises due to unwanted magnetic energy. Also, it is possible to obtain the induced voltage containing the third harmonic component in a magnetizing process which is further simplified by forming a given irregularity on the magnetizing surface of the magnet.

Title: Developing device and image forming device
Inventor: KOSUGE KATSUHIRO
IPC: G03G15/01
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a developing device and an image forming device capable of preventing the erroneous detection of the remaining toner amount by confirming the detecting operation, that is, whether the detecting operation by a remaining toner amount detecting means is normal or not. SOLUTION: Just after a toner hopper 5Y reaches a toner end position, the toner does not lie near a reflection polarization plate 11, because of an inertia of rotation, that is, the absence of the toner occurs. In the case a photodetecting signal is outputted from a toner end sensor 22 in such the toner absence state, it is decided that the toner end sensor 22 normally functions. On the contrary, in the case the photodetecting signal is not outputted in the toner absence state, it is decided that the toner end sensor 22 does not normally function and any abnormality occurs. In the case of deciding that it is abnormal in terms of the detection of the toner end sensor 22, an error display is displayed on a display part by a control part (neither of the parts are illustrated) so as to press a user for an inspection.
