    摘要: A printer includes a platen having a longitudinal axis and a printing head mounted in opposition to the platen. The guide shaft is mounted to extend parallel to the axis of the platen. A carriage supports the printing head and includes a carriage frame mounted on the guide shaft for movement axially therealong and for movement rotatably thereabout and a base plate having a first end integral with the carriage frame and a second end directed away therefrom. A guide plate is fixed at a position below the second end of the base plate and extends parallel to the guide shaft. A parallel link mechanism includes a fixing member attached to a lower surface of the second end of the base plate and a slider memebr connected to the fixing member. The slider member has a slot within which fits the guide plate, such that movement of the carriage axially of the guide shaft causes the parallel link mechanism and the second end of the base plate to be guided by the guide plate. An adjusting screw is threaded through a hole in the second end of the base plate and has a tip end in engagement with the slider member. Thus, upon rotation of the adjusting screw the slider member and the second end of the base plate are moved relatively toward or away from each other, thereby moving the carriage and the printing head rotatably about the guide shaft to increase or decrease the platen gap. A flexible member connects the slider member to the fixing member to prevent the slider member from becoming inclined relative to the guide plate.

    摘要: A method of forming an electrostatic latent image includes printing operation and toner recovering operation. The printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

    摘要: An image forming apparatus has a fixing unit. A heat roller heats a toner image on a print medium to fuse the toner image. A first temperature detector is in contact with a longitudinal end portion of the heat roller, and generates a first temperature data. A second temperature detector opposes the heat roller and is in proximity to a substantially middle portion of the heat roller. The second temperature detector generates a second temperature data. Depending on the first temperature data and the second temperature data, a controller performs temperature control either in a first mode where the heater is energized such that the first temperature data is equal to a first target value, or in a second mode where the heater is energized such that second temperature data is equal to a second target value.
