Abstract: PURPOSE:To obtain an electrophotographic sensitive body having good picture image characteristics without having reduction of resolution or defects in images and having an intermediate layer which has good productivity and can be produced at a low cost, by incorporating a spherical conductive inorg. powder into the intermediate layer. CONSTITUTION:An intermediate layer and a photosensitive layer are successively formed on a conductive base body. The intermediate layer contains a spherical conductive inorg. powder.

Title: Image-forming apparatus
Inventor: WADA ATSUSHI
IPC: G02B26/10
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To transmit horizontal synchronous signals without influences of noises by making a fall edge of a pulse frequency divided from a detection output pulse the horizontal synchronous signal to a laser of an odd number and transmitting a rise edge of the pulse as the horizontal synchronous signal to a laser of an even number. SOLUTION: Generated horizontal synchronous signals corresponding respectively to first and second lasers are frequency divided by an IC4 and transmitted as BDT signals to an IC3. The IC3 judges a fall edge of the transmitted BDT signal as the horizontal synchronous signal corresponding to the first laser and a rise edge as the horizontal synchronous signal corresponding to the second laser, and controls an image write position or the like. Since a pulse width of the BDT signal can be made twice a pulse width of a normal BD signal, even if countermeasures against extraneous noises are more intensely carried out to a transmission line for the BDT signal thereby making a signal waveform dull, the correct horizontal synchronous signal can be transmitted owing to the large pulse width.
