Title: Electrifying device and process cartridge or image forming device having electrifying device
Inventor: KOYAMA HIROSHI
IPC: G03G15/02
Filed: 1991-07-31
Abstract: PURPOSE:To obtain the electrifying device which enhances image quality and decreases noises by setting in such a manner that the ratio between the outside diameter of an electrifying member and the outside diameter of a body to be electrified is smaller than 2 and the outside diameter of the electrifying member does not exceeds the outside diameter of the body to be electrified. CONSTITUTION:The ratio Dd/Dc between the outside diameter Dc of the electrifying member 2 and the outside diameter D of the body 1 to be electrified of the electrifying device having the electrifying member 2 making contact with the body 1 to be electrified in order to electrify the body 1 to be electrified is so set that this ratio is smaller than 2 and Dc does not exceed Dc. The vibrating sounds generated by the impression of an AC voltage is empirically elucidated to be decreased by lowering the ratio Dd/Dc between the outside diameter of the electrifying member 2 which strikes the body to be electrified and the outside diameter of the struck body to be electrified. The Dd/Dc is satisfactory with the value smaller than 2 and is more preferably <=1.5. The effect of decreasing the vibrating sounds is not enough at >=2. While the effect of decreasing the vibrating sounds is remarkable if the Dc exceeds the Dd, the unnecessary large value thereof is undesirable as the electrifying device.

Abstract: PURPOSE:To reduce an erroneous operation due to a change in a disturbance light or a back ground temperature by a construction wherein a human body is judged to be present only when outputs of positive and negative polarities of an infrared ray detecting element exceed prescribed threshold values within a prescribed time. CONSTITUTION:A processing decision unit 4 sets prescribed threshold values V1 and V2 above and below an output bias value VB of an amplifier unit 3 so that V1 < VB < V2, and makes an output onto the positive polarity side only for a prescribed time T0 when VS < V2 in regard to a signal output VS of the amplifier unit 3, while making the output onto the negative polarity side when VS < V1, and the composite output of them is taken as an output of detection of a human body. Outputs of an infrared ray detecting element 2 and the amplifier unit 3 are delivered to be above and below the bias value VB, corresponding to an incident power. While the output is made onto the positive polarity side when the human body enters a detection area and onto the negative polarity side when it gets out of it, in other words, the output occurs on the positive polarity side in the case of a disturbance light only when the light enters the detection area. Next, the decision unit 4 detects the human body only when the output of the amplifier unit 3 occurs on the positive and negative polarity sides within the prescribed time. Accordingly, an erroneous operation can be prevented with regard to the disturbance light or a change in a background temperature.
