IPC: B41J2/39
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus in which stability can be enhanced in the writing position control of a latent image while lowering the applying voltage. SOLUTION: An image carrier 2 comprises a part having a resistive component R and a part having a capacitive component C formed sequentially on a conductive basic material 2a and has an electric equivalent circuit where the resistive component R and the capacitive component C are connected in series. A writing electrode 3b touches the part having a resistive component R and performs writing of an electrostatic latent image dominantly by injecting charges between the writing electrode 3b and the part having a resistive component R. An applying voltage is lowered significantly through charge injection. Since environmental effect is eliminated at the time of writing through charge injection, the latent image is written with no positional distortion and stability is enhanced in the writing position control of the latent image.  Furthermore, charges can be injected effectively between the writing electrode and the resistive component R by suppressing lateral leak of charges from the resistive component R and the capacitive component C.

IPC: H02P25/06
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the motor drive of a conventional laser beam scanner is not stabilized, and the shake angle of a mirror becomes unstable because oscillation is produced even on a 1/2 frequency fo2 when a gain is raised because the motor is driven with the driving current of a half wave waveform, and there are two peaks by the resonance frequency fo of the motor and the 1/2 frequency fo2. SOLUTION: A motor electric current control circuit 6 controlled by a control signal Vcnt in which an amount of driving current is defined by the bottom value of the amplitude of a detection signal Vf detected from the coil of a motor 1, filtered out, amplified, and phase-corrected, applies a driving current IDRV which has a current waveform inverting with each other, namely a sine wave or a waveform near the sine wave, and in which a harmonic content is almost removed, to a drive coil 1a. Thus, the driving current IDRV which has the sine wave or the waveform similar to the sine wave which does not contain the harmonic component synchronized with the resonance frequency is generated. By applying the driving current IDRV to the drive coil, the oscillation in the 1/2 frequency is prevented, motor drive is stabilized, and the shake angle and the shake state of the mirror are stabilized.
