摘要:
An image forming apparatus includes an image bearing member; recording material carrying member for carrying a recording material; a transfer charging member for transferring a toner image formed on the image bearing member onto the recording material carried on the recording material carrying member; a controller for controlling an electric current supplied from the transfer charger to the recording material carrying member to be a predetermined level; and potential applying device for applying a potential of the same polarity as that of the toner image to a backside of the recording material carrying member prior to transfer operation of the transfer charger.
摘要:
The present invention provides an image forming apparatus comprising an image bearing member for bearing an image thereon, and a transfer device for transferring the image from the image bearing member to a recording material at a transfer station. Wherein a limit value of electric power supplied to the transfer device is changed between a case where an imaged portion of the image bearing member is positioned at the transfer station and a case where a non-imaged portion of the image bearing member is positioned at the transfer station.

摘要:
An image forming apparatus includes a cylindrical image bearing member, an image forming device for forming an image on the image bearing member, a transfer unit for performing first image transfer of the image on the image bearing member to a recording material at a transfer position, and a movable recording material carrying unit for conveying the recording material to the transfer position while carrying the recording material in order to perform the first image transfer. The recording material carrying unit further carries and conveys the recording material in order to perform second image transfer to the recording material after the first image transfer. The apparatus also includes a conveying unit for conveying the recording material to the recording material carrying unit. The recording material is first conveyed by the conveying unit to a position within the radius R of the image bearing member at the upstream side in a moving direction of the recording material carrying unit from the transfer position on the recording material carrying unit.

A cleaning device including a flexible member to be cleaned, a cleaning unit for cleaning a surface of the member to be cleaned, the cleaning unit including a cleaning web in contact with the member to be cleaned, and a potential applying member, provided on an opposite side of the member to be cleaned from the cleaning web, for applying a predetermined potential to the member to be cleaned. The potential applying member is provided at substantially the same position as the cleaning web in a direction of movement of the member to be cleaned.
摘要:
An ink jet printing apparatus includes an ink jet printing unit for executing ink jet printing on a printing medium by use of an ink jet printing head, a heat application treatment unit arranged below the ink jet printing unit for executing heat treatment to a printing medium after the execution of ink jet printing in the ink jet printing unit, and a heat insulating member arranged between the ink jet printing unit and the heat application treatment unit. Thus, this apparatus is made capable of preventing heat generated by the heat application treatment unit from producing any unfavorable effect that may invite the degradation of printing quality if such heat is transferred to the various members in the apparatus, such as the ink jet printing unit, the printing medium storage unit, or to the bending portion of a printing medium between the ink jet printing unit and printing medium storage unit.
摘要:
The present invention provides an image forming apparatus which comprises an image bearing member, a recording material bearing member for holding and conveying a recording material to a transfer portion, a transfer charge member for transferring an image from the image bearing member to the recording material born by the recording material bearing member, and an urging means for urging the rear surface of the recording material bearing member in the vicinity of the transfer portion. The transfer charge member being contacted with a rear surface of the recording material bearing member opposite to a front surface on which the recording material is held at the transfer portion.
摘要:
An image forming apparatus utilizing an ink jet recording head and including a plurality of processing devices for forming the image; a detector which detects a quantity of a state, i.e. temperature, humidity, idle time, suspened dust, etc., related to a control of the image processing devices; and an inferrence computer which uses fuzzy logic in analizing the detected quantity of state to control the processing devices.
摘要:
An ink jet recording apparatus with plural full-line type recording heads has a heat pipe associated with each recording head. The heat pipes are connected together at a common portion in various ways, such as by a heat-conductive block, one or more additional heat pipes or a container with a heat transferring liquid medium. Such an arrangement enables more efficient and compact temperature control of the recording heads.
