Title: Developing device
Inventor: ENOKI SHIGEKAZU
IPC: G03G15/06
Filed: 1985-11-19
Abstract: PURPOSE:To enable reversal development and to obtain sharp visible images by setting the external resistance of the outside layer of a toner carrier so that the electrostatic charging polarity of toner part is maintained. CONSTITUTION:A visible image obtained through the reversal development of a developing device 100 is transferred onto transfer paper 9 by a transfer charger 8. The charge wire of the transfer charger 8 is applied with a plus voltage and toner which is charged negatively is moved from a photosensitive body to the transfer paper side. The photosensitive body after the transfer has remaining toner cleaned by a cleaning device 10 and is discharged electrostatically by a static eliminator. The electric resistance value of the outside layer 24 is set high so that toner particles facing an electrostatic latent image X are uncharged electrostatically or inverted in polarity owing to a leak of its negative charges to the outside layer 24 of a developing roller 4 during developing operation, thereby maintaining the polarity of the previously charged toner particles throughout the developing operation. Consequently, no toner particles stick on the electrostatic latent image X and toner particles stick on only a part Y other than the latent image, so that a sharp visible image is obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent an opening of a valve element from principally deciding even if an input current value becomes zero in an electric driving part by increasing set pressure according to reduction of the input current value, and setting the set pressure to the maximum value when the input current value exceeds zero. SOLUTION: A capacity control valve 46 is formed in such a constitution that set intake pressure is set to the maximum value when a current value inputted to a coil 70 exceeds zero. An sensitive chamber 56 of the capacity control valve 46 is communicated with an intake chamber 37 through a pressure detecting passage 47.

Title: Output circuit
Inventor: YOSHINO KENJI
IPC: H03K5/13
Filed: 1992-09-28
Abstract: PURPOSE:To prevent the increase of the power consumption and also to reduce the deterioration of slow rate caused by the increase of the output load. CONSTITUTION:A delay decrease signal PHIX is inputted when the through rate must be improved in response to the increase of the output load. An output accelerator 10 improves the delay of at least the rise or the fall of the output of a relevant output circuit when the signal PHIX is inputted. This is due to a fact that a p-channel MOB transistor TR TP2 is connected in parallel to a p-channel MOS TR TP1 or a fact that an n-channel MOB TR TN2 is connected in parallel to an n-channel MOS TR TN1. Whether the slow rate of an output signal out is improved or not can be selected and therefore the increase of the average power consumption can be prevented.
