An image forming apparatus includes a photosensitive drum; an exposing unit to expose the photosensitive drum to form latent images to the respective colors of one print; a developing device to develop the latent images formed on the photosensitive drum; an intermediate transfer belt abutting against the photosensitive drum, to temporarily hold a toner image; a secondary transfer roller contacted/retracted with respect to the intermediate transfer belt to transfer the toner image to a document; an intermediate transfer member cleaner contacted/retracted to/from the intermediate transfer belt to remove residual toners left on the intermediate transfer belt, wherein the secondary transfer roller contacts the intermediate transfer belt before operations of the exposing unit are accomplished with all colors of toner images in one print, and is retracted from the intermediate transfer belt before a next print is commenced.

An active matrix substrate includes base substrate, gate lines, data lines, thin-film transistors and pixel electrodes. The gate lines are formed on the base substrate. The data lines are formed over the gate lines. Each of the data lines crosses all of the gate lines with an insulating film interposed therebetween. The thin-film transistors are formed over the base substrate. Each of the thin-film transistors is associated with one of the gate lines and operates responsive to a signal on the associated gate line. Each of the pixel electrodes is associated with one of the data lines and one of the thin-film transistors and is electrically connectable to the associated data line by way of the associated thin-film transistor. Each of the pixel electrodes and the associated thin-film transistor are connected together by way of a conductive member. Each of the pixel electrodes crosses one of the gate lines, while the conductive member for the pixel electrode crosses another one of the gate lines that is adjacent to the former gate line.

A plurality of microwave introduction windows are placed at the top wall of the reaction chamber. Microwaves of the same power are introduced into, e.g., two microwave introduction windows that are equivalent in location relationship with respect to the sidewall of the reaction chamber, while microwaves of different power are introduced into, e.g., two microwave introduction windows that are non-equivalent in location relationship with respect to the sidewall. Thus, a cost-effective plasma process apparatus is obtained which can realize uniform plasma processing even if the plasma being generated within the reaction chamber has varied load impedance.

A cleaning mechanism for an image forming apparatus has a cleaning roll that contacts an intermediate transfer body under pressure with a predetermined load and rotates with the intermediate transfer body for removing residual ink, toner or impurities on the intermediate transfer body after a transfer process. A sheet member is urged onto the cleaning roll for slip contact with a predetermined load.

A thin-film transistor of the reversed stagger type is provided with a gate electrode, first and second gate insulating films, a semiconductor layer, separated contact layers, and source electrodes and drain electrodes, all of which are stacked on a substrate. Upon manufacturing the thin-film transistor of this type, a gap section is pattered in a single contact-material layer. In this case, the contact-material layer is patterned by a dry etching with etching gases including HCl+SF6 or CF4+O2+HCl by the use of the source electrode and drain electrode as direct masks. Upon patterning a gap section in the contact-material layer between the source electrode and the drain electrode, no dedicated resist pattern is required; therefore, it is possible to reduce the number of the processes as compared with conventional manufacturing methods. Consequently, it becomes possible to reduce the production cost of thin-film transistors and also to improve the yield of desired products.
