Title: Electrophotographic developing agent, its production and image forming device
Inventor: AJIMA HISANOBU
IPC: G03G9/08
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To improve smear property and offset property, to decrease a contamination on a photoreceptor and to improve fluidity of a developing agent by controlling the ratio of wax content in a toner particle to wax content in the whole toner to a specified value. SOLUTION: The developer has such a structure that coloring agent particles 2 and wax 3 are dispersed in a binder resin 1. The wax 3 is easily pulverized and forms an interface during pulverization compared to other source material, so that if the dispersion is bad, the amt. of the wax included in the toner decreases while the amt. of wax included in a classified fine power increases. In the method, the volume average particle size is 8 to 12μm and the amt. of wax (w) included in particles of (volume average particle size)-3μm particle size and the amt. of wax (w) in the whole toner are controlled to satisfy w/W=1.00 to 1.20. Namely, when the ratio is 1.0 to 1.2, extremely good dispensability of the wax in the toner is obtd. The nearer the ratio is to 1.0, the more uniformly the wax is dispersed in the toner.

Filed: 1991-08-13
Abstract: PURPOSE:To places the warning device in normal warning operation at all times even when the kind of a line connected to the warning device is changed for some reason during the operation of the warning device. CONSTITUTION:In case of a failure in the starting warning operation of a telephone set circuit 2, a controller 4 considers that the line kind is changed from, for example, a PB(bush-button) line to a DP(dial pulse) line and sends the indication for the transmission of a dial pulse signal to the telephone set circuit 2 through a network controller 1 to urge the actuation of an exchange. At this time, the warning operation is successful, the line connected to the warning device is recognized as the DP line and stored in a storage device and a DP tone signal is sent in subsequent warning operation. Therefore, the warning is possible regardless of the kind of the line connected to the warning device and the accuracy of the warning operation is improved.
