摘要： A sheet conveyance guide (31) is composed of separation claws (32) for separating the paper from a conveyer and transfer belt (216) and a movable sheet guide (33) for guiding the paper to a fixer entrance sheet guide (30). The separation claws (32) are arranged on the upstream side of the movable sheet guide (33). The movable sheet guide (33) is rotatable about a pivot shaft with its distal end abutted by gravity upon the upstream end part of the fixer entrance sheet guide. The separation claws and movable sheet guide are axially supported so as to rotate on pivots. The sheet conveyance guide moves together with the vertical movement of the conveyer and transfer belt while the abutment point of the separation claws upon the conveyer and transfer belt moves to the appropriate position.

摘要： The image forming apparatus includes: an image forming portion having a multiple image forming stations each forming a color separated image; a transfer device for superimposing and transferring color separated images; a pattern image forming device for forming a predetermined pattern image; a pattern image density measuring device for measuring the density of the pattern image. In this configuration, the pattern image is formed so as to be greater than the measuring area of the pattern image density measuring device and is formed of multiple lines having a line width and a line spacing so that any part of the pattern image within the measuring area will produce an approximately constant measured density value. The image forming apparatus further includes a timing control device which performs control in such a sequence that one image forming station to be the reference, in the image forming portion, a pattern image; the image forming station to be adjusted forms another pattern image, which is superimposed over the pattern image formed by the reference image forming station; the pattern image density measuring device measures the density of the superimposed pattern image so as to judge the superimposed state of the pattern image based on the measured density; and the image forming station to be adjusted is controlled so as to perform image forming at a timing so that the measured density will fall within a predetermined permissible density range.

摘要： In a paper-punching device (33) for use in an image-forming apparatus, the rear edge of a sheet of paper that is being transported through a transport guide is detected by the photosensor (32). After a predetermined time has passed since the detection, a punching device (33) is activated. At this time, a punching member (38) is depressed downward, and a punching blade (38a) attached to its top penetrates through the sheet of paper, thereby forming a punch hole. Even during the punching operation, transport rollers (34,35) continue to rotate. Therefore, when the sheet of paper is caught by the punching blade (38a), the transport rollers (34,35) are allowed to make a slip at a predetermined amount with respect to the paper. For this reason, at least one of the transport rollers (34,35) is made of a foamed material. With this arrangement, since the punching operation is carried out on the rear side of the sheet of paper, it becomes possible to reduce the occurrence of paper jams even if sheets of paper are transported in succession. Further, the punching operation is carried out while the paper is being transported; this makes it possible to provide a high-speed operation. Further, even if the sheet of paper is caught by the punching blade, it is not damaged because the slip is provided.
