摘要： A pair of registration rollers are provided upstream in a paper transport path from an image forming position, and a paper transport position detection portion is provided upstream in the paper transport path from the pair of registration rollers. When consecutive print processing on a plurality of sheets of paper is performed, a paper transport position in the paper transport path is detected by the paper transport position detection portion for a sheet of paper that has been set in advance among the plurality of sheets of paper. A correction amount of a position for image writing to a photosensitive drum is determined based on the paper transport position, and correction of the image writing position is performed based on the correction amount. Image forming on the sheet of paper is performed at the image forming position based on the image writing position after correction, and image forming on other sheets of paper after the sheet of paper that was set in advance is performed at the image forming position based on the image writing position after correction.

摘要： A rewritable, nonvolatile memory includes a first region having stored therein a processing program which allows an electronic device to perform a process, and having a first specific portion which is accessed first upon boot-up by the electronic device; and a second region having stored therein a boot program and a rewrite program. Upon erasing storage contents of the first region, the storage contents of the first region are erased by the rewrite program such that a storage content of the first specific portion is erased last. Upon writing storage contents into the first region, new storage contents are written into the first region by the rewrite program such that a storage content of the first specific portion is written first.

摘要： The image forming apparatus includes: a paper feed unit; a print unit; a registration roller; a sheet leading end sensor provided downstream, in a transport direction of the recording paper, of the registration roller; a time measuring unit for measuring a time from a start point of transportation of the recording paper by the registration roller to a point of detection of the leading end of the recording paper by the sheet leading end sensor; a memory unit for storing a reference image forming time and a reference time; a print control unit; and an arithmetic unit for obtaining a difference between the reference time and the time detected by the time measuring unit. The print control unit adjusts the length of the image forming period in accordance with the adjusted image forming time determined based on the difference obtained by the arithmetic unit and the reference image forming time.
