摘要:
There is disclosed a manufacturing method of highly integrated circuits with thin-film transistors (TFTs) for use as peripheral driver circuitry in active-matrix liquid crystal display (LCD) panel with a pixel array each having a charge transfer control TFT, capable of facilitating formation of contact holes otherwise being difficult in cases where an anode oxide film is formed on gate electrodes of TFTs and lead wires both of which are made of anodizable metal, such as aluminum. The method includes execution of anodization while causing a resist mask to be disposed on part of the lead wire and electrode made of aluminum, thereby partly eliminating formation of the anode oxide film on the lead wire and electrode. At a later step of fabrication, each contact is formed by use of such portion that has no anode oxide film formed thereon. This may allow aluminum to be employed as lead wires while enabling easy fabrication of contacts therefor.

A developing device for an image forming apparatus includes both a layer height restricting blade for controlling a thickness of the developer layer on a developer supply roller, and a spike-height restricting blade. The spike-height restricting blade is located downstream from the layer height restricting blade, and upstream from the position at which an electrostatic latent image bearing member and the developer supply roller are closest to each other. Preferably, the tip of the spike-height restricting blade is located downstream from a radial line along which a main magnetic pole of the device projects half of its maximum magnetic field strength.

A method for forming an insulator film at a semiconductor temperature of 600° C. or less comprises the steps of forming a first insulator film by oxidizing a surface of a semiconductor in an atmosphere containing oxygen atom radicals, and forming a second insulator film on the first insulator film by deposition without exposing the first insulator film to outside air.

A transfer device and an image forming apparatus capable of forming an image of smooth image quality with little uneven density, are provided. An alternating voltage is applied so that a first period in which a first peak-to-peak voltage Vpp(1) is applied and a second period in which a second peak-to-peak voltage Vpp(2), lower than the first peak-to-peak voltage, is applied are alternately repeated. In the alternating voltage to be applied, a transfer side potential to shift a toner from an intermediate transfer belt to recording paper sheet and an opposite transfer side potential to shift the toner from the recording paper sheet to the intermediate transfer belt are applied so as to alternate with each other. When f1 denotes a frequency of the first period and f2 denotes a frequency of the second period, f1=f2 is satisfied.

There is provided an image forming apparatus capable of realizing improvement of an image density by improving dot reproducibility and reducing fog at the same time. An alternating voltage is applied to a development sleeve so that a first period during which a first peak-to-peak voltage Vpp(1) is applied and a second period during which a second peak-to-peak voltage Vpp(2) that is lower than the first peak-to-peak voltage is applied are repeated alternately. The alternating voltage to be applied is applied so that a development-side potential to move toner from the development sleeve to a photoreceptor and an opposite development-side potential to move toner from the photoreceptor to the development sleeve alternate with each other. The potential to be finally applied in the first period is preferably the development-side potential.
