An image forming method, includes a charging step of charging an image carrier; an image writing step of writing image data onto the image carrier; a developing step of developing a latent image area written by the image writing step on the image carrier; a transferring step of transferring a toner image developed by the developing step to a transferring member; an image writing position adjusting step of detecting a position of the image carrier where the image is written in a case where designated conditions are satisfied, and of adjusting an image writing position; and a voltage output control step of controlling voltages applied for charging, developing, and transferring in the charging step, the developing step, and the transferring step, respectively.

Image forming method, image forming device, and image forming program

An image forming apparatus includes a photosensitive member driving part that drives a photosensitive member, a counting part that carries out an adding operation when the photosensitive member driving part drives the photosensitive member, and carries out a subtracting operation when the photosensitive member driving part stops the photosensitive member; and a control part that interrupts, when a count value of the counting part becomes equal to or more than a first predetermined value, a printing operation of driving the photosensitive member, forming an electrostatic latent image on the photosensitive member, and fixing a toner adhering to the photosensitive member onto a recording sheet, and causes the counting part to start the subtracting operation.

Image forming apparatus, printing operation control method and computer-readable information recording medium

An image forming apparatus includes an image forming unit, a conveyor unit, a printing unit, a data acquiring unit, and a control unit. The image forming unit forms an image based on image data. The conveyor unit conveys a transfer medium onto which the image is to be transferred. The printing unit prints the image onto the transfer medium. The data acquiring unit acquires the image data. The control unit controls the conveyor unit, the printing unit, and the data acquiring unit. The control unit controls the conveyor unit not to feed a transfer medium from a feed tray to the printing unit when a command for printing a second side by double-sided printing is not detected within a predetermined time after detecting a command for printing a first side by double-sided printing.

Image forming apparatus, print control method, and computer product

An image forming apparatus includes a counting unit that, when a driving unit for rotating an image carrier is operating, adds a predetermined first count value to a total count value in a predetermined timing and that, when the driving unit is being stopped, subtracts a predetermined second count value from the total count value in every predetermined timing; and a suspending unit that suspends printing when the total count value becomes equal to or larger than a preset suspend value.

Image forming apparatus with a counting unit

A process unit is removably attached inside a main body of an image forming apparatus. The process unit includes a casing and a latent image carrier housed inside the casing. The latent image carrier can rotate in a forward direction and a reverse direction. An ID chip is provided in the process unit for storing various information. A communication unit arranged in the main body can communicate with the electronic-information storage unit to write information in or read information from the ID chip. A control unit provides control so that the communication unit does not communicate with the ID chip when the latent image carrier is rotating in the reverse direction.

Image forming apparatus

An image forming apparatus includes image-forming process cartridges arranged in tandem; a color-information acquiring unit configured to acquire color information representing a color of an image to be formed by each of the image-forming process cartridges; an image-information distributing unit configured to distribute print information for the color to an image-forming process cartridge that forms an image of the color; a designating unit configured to designate a print mode that includes a monochromatic mode and a full-color mode; a control unit configured to control image forming operation by the image-forming process cartridges to perform a print operation in designated print mode; and an alarming unit configured to generate an alarm for designation for the full-color mode when the color is identical in two or more image-forming process cartridges.
