Abstract: The image forming apparatus includes a photosensitive drum, an image forming unit, an intermediate transfer belt, a circuit of a drive motor which outputs information on a moving distance, a registration roller, a CPU which calculates the predetermined timing on the basis of the information on the moving distance output by the circuit of the drive motor at the time when a rotation speed of the intermediate transfer belt is switched from a first process speed to a second process speed, and a memory storing the information on the predetermined timing calculated by the CPU, wherein the CPU controls the registration roller so as to start the conveyance of the recording material at the predetermined timing stored in the memory. Consequently, a positional relation between a leading end of the recording material and a leading end of the image formed on the recording material can be set as a desired positional relation.

Abstract: A solution-receiving plate having solution-passing holes for passing a developer solution therethrough toward the back side of the plate is provided. Respective surfaces of the solution-receiving plate and a substrate are at the same height, and the solution-receiving plate is placed on the front-end side of the substrate and separated slightly from the front end of the substrate. A supply nozzle is moved to apply a developer solution. Accordingly, when the developer solution extended continuously between the perimeter of the substrate and the supply nozzle is severed, the severed developer solution is prevented from returning to the developer solution already spread over the substrate and thus flow and waves are prevented from occurring in the developer solution spread on the surface of the substrate. A resist pattern with a highly uniform line width is thus produced.

Accordingly, a state of special air flow at an outer edge portion of a substrate to be processed can be eliminated, thereby preventing an increase in film thickness at the outer edge portion.

Abstract: A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view.

Abstract: To provide an image forming apparatus having a plurality of optical systems each simultaneously scanning two stations by one polygon mirror to minimize conveyance-directional color misregistration of an intermediate transferring belt. An electrophotographic color laser printer connected with a host computer is provided with a scanner unit common to first and second stations, a scanner unit common to third and fourth stations, and a registration-position detector for reading an image pattern formed on an intermediate transferring belt and detecting a registration position of an image of a laser beam. The plane phase of the polygon mirror in the first and second stations is controlled and central positions of image patterns by two laser beams are detected to correct the misregistration between these central positions.
