摘要： An image transfer device includes an image transfer electrode roller which is disposed face to face with a photosensitive drum with a printing sheet passing between the image transfer electrode roller and the photosensitive drum. The image transfer device is structured such that the image transfer electrode roller can be shifted back and forth along a transport direction of the printing sheet. A voltage is applied to the image transfer electrode roller to create an image transfer electric field between the image transfer electrode roller and the photosensitive drum for transferring a toner image formed on the photosensitive drum onto the printing sheet. The image transfer electrode roller is brought to one of different positions along a transport direction of the printing sheet selected according to information on properties of the printing sheet and transfers the toner image onto the printing sheet at that position.

摘要： Transfer roller(s) is/are such that either end thereof is formed from fibrous electrically conductive component(s) and such that cylindrical portion(s) in central region(s) is/are, for example, formed from metal roller-like structure(s), either fibrous electrically conductive component outer end being arranged so as to extend somewhat beyond either transfer/transport belt side. Furthermore, outside diameter(s) approximated by tips of respective individual fiber(s) of fibrous electrically conductive component(s) is/are somewhat larger than diameter(s) of metal roller-like structure(s). This makes it possible for electric field(s) to be applied, and for charging to occur, along the full width(s) of transfer/transport belt(s).

摘要： A timer clocks and accumulates time periods during each of which a recording sheet is transported or transfer bias is applied as transfer execution periods. When the accumulated value reaches a predetermined value, the timer outputs a time-up signal to a CPU and then clears the accumulated value. The CPU executes a cleaning operation at the time the time-up signal is inputted from the timer. In the cleaning operation, the CPU causes a high-voltage power source to apply cleaning bias to a transfer electrode roller while causing a high-voltage power source to apply delivery bias to an auxiliary cleaning roller, in order to return toner attracted to the auxiliary cleaning roller to a photosensitive drum via a transfer belt.

摘要： An image recording apparatus includes a first pullout unit, a second pullout unit, and a first lock mechanism. The first unit is movable along a first axis between a first retracted position where the first unit is fully retracted in the apparatus, and a first exposed position where at least one side surface thereof is fully exposed to the front of the apparatus. The second unit is movable along a second axis, which is perpendicular to the first axis, between a second retracted position where the second unit is fully retracted in the first unit, and a second exposed position where the second unit is exposed to a side of the side surface of the first unit. The first lock mechanism prevents movement of the second unit from the second retracted position to the second exposed position when the first unit is not in the first exposed position.

摘要： A control portion obtains a first difference in a movement amount between paper passing period and paper non-passage period of a transfer belt, and determines whether or not a first absolute value thereof is a first threshold value or more. In a case where the first absolute value is the first threshold value or more, a transfer belt unit positional adjustment motor is driven to adjust a first angle with respect to a first direction of a transfer belt unit with respect to a photoreceptor drum. In a case where the first absolute value is less than the first threshold value, a second absolute value of a second difference between a movement amount and a designed value set in advance of the transfer belt is obtained, and whether or not the second absolute value is a second threshold value or more is determined. When the second absolute value is less than the second threshold value, the processing is finished, and when the second absolute value is the second threshold value or more, a second angle with respect to a second direction orthogonal to the first direction of the driving roller with respect to the photoreceptor drum is adjusted so as to be less than the second threshold value by a driving roller positional adjustment motor.
