An image forming apparatus includes a printing device, a nipping rotator, an upstream support stand, a plurality of rotators, a supporter, and an adjusting mechanism. The printing device prints an image on a plate-shaped printing medium. The nipping rotator conveys the plate-shaped printing medium. The upstream support stand supports the plate-shaped printing medium at a position upstream from the nipping rotator in a conveyance direction of the plate-shaped printing medium. The plurality of rotators are disposed side by side. The supporter supports the plurality of rotators. The adjusting mechanism adjusts relative positions of the plurality of rotators and the supporter.

Image forming apparatus

An image forming apparatus includes a printing device, a rotator, an upstream support stand. The printing device prints an image on a plate-shaped printing medium. The rotator rotates while nipping the plate-shaped printing medium and conveys the plate-shaped printing medium to the printing device. The upstream support stand supports the plate-shaped printing medium at a position upstream from the rotator in a conveyance direction of the plate-shaped printing medium and includes a mount. The mount is detachably attached to the rotator.

An image forming apparatus includes a carriage configured to scan with an ejection head for ejecting ink droplets that harden when exposed to active energy line onto a recording medium to form an image and an emitter unit for emitting the active energy line mounted thereon, and an image forming controller configured to control ejection of the ink droplets from the ejection head and scan of the carriage. The image forming controller forms an ink droplet film of an uppermost layer of an image made of multiple layers of ink droplet films with finer image quality than that of an ink droplet film of each lower layer other than the uppermost layer, and forms the ink droplet film of the each lower layer other than the uppermost layer with coarser image quality and in a shorter length of time than a length of time taken to form the uppermost layer.

A head drive control unit generates and outputs a pulse formed of a first expansion waveform element to expand individual liquid chambers, a first contraction waveform element to contract the individual liquid chambers, a second expansion waveform element to expand the individual liquid chambers, and a second contraction waveform element to return the individual liquid chambers that have repeatedly expanded and contracted to an initial state. The first contraction waveform element serves as a waveform element that contracts the individual liquid chambers at a timing of resonance with a change in a pressure in the individual liquid chambers due to the first expansion waveform element. The second contraction waveform element serves as a waveform element that suppresses the change in the pressure in the individual liquid chambers.

A circuit device drives actuator elements respectively associated with a plurality of nozzles to cause droplets to be ejected from the nozzles. The circuit device includes input terminals; a receiving unit; a switching unit; and a transfer unit. The receiving unit receives, via the input terminals, input signals including a terminal arrangement signal and drive signals for driving the actuator elements. The terminal arrangement signal indicates a type of assignment of signals to be assigned to the input terminals. The switching unit switches the assignment of signals in accordance with the terminal arrangement signal. The transfer unit transfers, to the actuator elements, drive signals that are input to the input terminals after the assignment of signals has been switched.
