An image forming apparatus has a plurality of image forming stations capable of forming different images which are to be correctly registered and superimposed. Elimination of possible image misregistration in each image station is executed on the basis of the result of detection of register marks which are formed by each image forming station. The correction is executed at a timing which is independent from image forming sequences performed by each imgae forming station in accordance with image signals, e.g., during warming-up of the apparatus after the initial application of the power immediately after the input of image forming operation start instruction through a start key, or after completion of production of a predetermined number of copies counted from the last misregistration correcting operation.

An image forming apparatus has a photosensitive member for carrying an image, an exposure device for exposing the photosensitive member to form a latent image on the same, a development device for developing the latent image on the photosensitive member with a toner to form a toner image, a transfer member carrier for supporting and conveying a transfer member to a transfer position on the phtosensitive member, a first conveyance mechanism for conveying the transfer member to the transfer carrier member, and a second conveyance mechanism for conveying the transfer member to the first conveyance mechanism. A cancellation mechanism is provided to cancel a transfer member conveying force of the first conveyance mechanism after a leading end of the transfer member conveyed by the first conveyance mechanism has been supported on the transfer member carrier. A trailing end of the transfer member passes through a nip of the second conveyance mechanism during a period of time when the transfer member conveying force of the first conveyance mechanism is canceled by the cancellation mechanism and when the exposure device is not operating. In this arrangement, vibration generated when the transfer member is conveyed to the transfer member carrier by the first and second conveyance mechanisms is prevented from affecting the latent image formation made by the exposure device.

An image forming apparatus such as a laser beam printer has a plurality of movable image carrying members such as photosensitive drums, an image forming member such as a laser beam scanner capable of forming on the image carrying members images of different colors correspoding to image information, and transfer devices for sequentially transferring the image carried by the image carrying members to an image receiving member such that the image of different colors are superposed. The image receiving member may be copy paper or an overhead projector sheet, and is fed by a feeding device in the form of an endless belt. A lifting device is provided to move the feeding device from an operative position to at least one retracted position in response to detection of jamming or when an image receiving member having a large heat capacity is used.

An image forming apparatus for forming an image on a sheet has a first conveyance path for guiding the sheet, and a second conveyance path arranged in continuation from the first conveyance path to guide the sheet conveyed from the first conveyance path. A conveyor drum, which may be an image transfer drum, retains the sheet on its surface and conveys the sheet such that the sheet moves along said second conveyance path. The drum and the second conveyance path are supported such that they can be moved in a direction which intersects the direction of sheet conveyance, so as to be drawn out of the main part of the apparatus. A sheet jam detector is provided for detecting a sheet jam at a predetermined position which is on the drum and which is spaced from the inlet of the second conveyance path by a distance greater than the length of the sheet which has the greatest length among the sheets which are to be handled by the apparatus, as measured along the second path. A plurality of conveying rollers located within the first and second conveyance paths are selectively rotated to ensure that a trailing end of the sheet passes the inlet of the second conveyance path. A space is provided within the second conveyance path for accommodating bulging of the sheet during that process.

A roll sheet conveying device includes a spool arranged to be rotatable while holding a roll-shaped sheet, a sheet conveying roller for driving and conveying the sheet, and a spool brake mechanism for generating a rotation load to act on the spool, wherein, when the sheet is sent out from the spool by driving the sheet conveying roller, the rotation load of the spool brake mechanism is caused to act on the spool, and when the sheet is rewound onto the spool by driving the spool, the rotation load of the spool brake mechanism is prevented from acting on the spool.
摘要:
An ink jet textile printing apparatus for performing printing by reading an original image created by a designer, converting the original image into original data represented by an electric signal, retrieving the original data for processing to be output as image data, and recording data on cloth based on the image data. The ink jet textile printing apparatus has a first ink jet recording head provided upstream of a recording position, and a second ink jet recording head provided downstream thereof, and is provided with a drying unit located between the recording heads, whereby high-quality recorded images with less bleeding can be obtained by recording on a recording area again with the second ink jet recording head after drying the recording area on the cloth recorded by the first ink jet recording head with the drying unit.
