The second basis weight is larger than the first basis weight. The second temperature is higher than the first temperature. The second period is longer than the first period.

The image forming apparatus is an image forming apparatus for forming an image on a recording material using an electrophotographic process, and includes a transfer section that transfers a toner image on an image bearing member onto a transfer-receiving member; and a hardware processor (transfer voltage controller) that controls a transfer voltage to be applied to the transfer section by correcting a reference transfer voltage with a correction amount that is based on an environmental change, wherein, the correction amount depends on at least the transfer voltage, and the hardware processor determines the correction amount for determining the transfer voltage for a current transfer by referring to the transfer voltage for an immediately preceding transfer.

An image forming apparatus according to the present disclosure includes: a hardware processor configured to control an image former on a basis of a job pertaining to a printing execution command. The hardware processor is configured to divide the job pertaining to the printing execution command into a plurality of short jobs, and configured to stop conveyance of the roll sheet and forcibly eject degraded toner from a developing device of the image former at a pause timing between short jobs temporally adjacent to each other among the plurality of short jobs; and the hardware processor sets a job content of each of the plurality of short jobs such that an image of a printing target is inverted upside down for each job switching of the plurality of short jobs.

Disclosed is an image forming apparatus, which may be capable of forming an image on a continuous print medium and which may include: a fixing part that may come in contact with and heat a continuous print medium so as to fix an image formed on the continuous print medium; and a hardware processor that may perform temperature rise control of the fixing part. The fixing part may be capable of performing temperature rise control of the fixing part in a state where the contact of the fixing part with respect to the continuous print medium is released and the continuous print medium is stopped, and the hardware processor may prohibit the temperature rise control of the fixing part in a case where the hardware processor determines that a tension is not uniformly applied to the continuous print medium.

Provided is an image forming system which optimizes subsequent processes for crossing paper when a causing apparatus has stopped in the state in which paper is spanning the causing apparatus and a downstream apparatus. The image forming system conveys the paper from a first apparatus (the causing apparatus) to a second apparatus (the downstream apparatus) connected to the first apparatus. The image forming system 1 includes a conveying unit and a hardware processor. The conveying unit conveys the paper. The hardware processor determines, in a case where the paper is normally conveyed by the conveying unit across the first apparatus and the second apparatus, whether processes of the first apparatus has been completed for crossing paper which is the paper spanning the first apparatus and the second apparatus, when the first apparatus stops due to an abnormality.

The invention relates to a printing machine with hybrid printing technology for printing on a continuous material web. In order to create a printing machine with hybrid printing technology which is adaptable and flexible in use in the course of the current trend for digitization, the printing machine with according to the invention, hybrid printing technology for printing a continuous material web, is a printing machine with a rotating central cylinder, on the surface of which the material web is guided from a placement point to a separation point for printing; a plurality of inking units for digital printing of the material web are arranged in the region of an upper half of the central cylinder, and a plurality of inking units for flexographic printing of the material web are arranged in the region of a lower half of the central cylinder; an unwinding station is provided for unwinding the material web to be printed from a roll and a winding station is provided for winding the printed material web onto a roll, the unwinding station and the winding station being arranged on a first side of the central cylinder, with supply guide rollers for feeding the material web unwound from the unwinding station to the central cylinder and with discharge guide rollers for discharging the printed material web from the central cylinder to the winding station; the feed guide rollers and the discharge guide rollers being arranged on a second side of the central cylinder, with a feed guide roller for placing the material web onto the central cylinder at the placement point and a strip guide roller for detaching the material web from the central cylinder, the feed guide roller and the strip guide roller being designed in such a way that the placement point and the separation point are arranged on the lower quadrant of the central cylinder.

An image forming apparatus includes a first conveyor, a cutter, a second conveyor, a detection image forming section, a detector, and a controller. The first conveyor conveys a print medium. The cutter cuts the conveyed print medium. The second conveyor conveys, in a first direction, the print medium cut by the cutter. The detection image forming section forms a detection image on the print medium and the second conveyor. The detector detects, at two positions in a second direction, the detection image formed on the print medium or the detection image formed on the second conveyor. The controller varies one or both of a conveying speed of the print medium to be conveyed by the first conveyor and a cutting speed of the print medium to be cut by the cutter, on the basis of a comparison of the detection image detected at the two positions.

Compact hybrid developing machine that exposes a photosensitive substrate (1) using an LED or LCD display (2,3) wherein the substrate (1) is placed in direct contact with the image generating layer (colour generating layer+channelling layer) of the display (2,3). When the display is of LCD technology, the filters (21) of the colour generating layer are placed closer to the substrate (1) than the liquid crystal layer (22). In both types of display (2,3), a channelling layer is installed within the image generating layer, for example, a black matrix (4) of opaque elements. When using an LCD display (2), this may have a unifying filter (24) or a black translucent filter (25) before the light diffusing layer.
