An image forming device includes a first carriage path for carrying paper stored in a paper feeding tray to a printer, there is a second carriage path for carrying paper stored in a second paper feeding tray to the printer. The first carriage path and the second carriage path individually carry a paper to the printer.

A fixing device includes a fixing roller, a single heating member that heats the fixing roller, a pressure roller, a first temperature detecting element that detects the temperature of the contact region, of the fixing roller, that comes into contact with the recording paper transported, and a second temperature detecting element that detects the temperature of the noncontact region of the fixing roller. The fixing device carries out energization control of the heating member based on the temperature detected by the first temperature detecting element and stops energization control of the heating member when the temperature detected by the second temperature detecting element reaches a prescribed temperature.

An image forming apparatus includes a history storage portion for storing the usage history involving the number of prints of the image forming apparatus, and a processing time controller for changing the time of the pre-processing operation before or the time of the post-processing operation after a printing process of the printing portion, based on the stored usage history so as to exclude the influence of the unfixed developer on the printing process.
摘要:
One embodiment of an image forming apparatus according to the present invention is an image forming apparatus in which registration rollers are arranged immediately before an electrostatic latent bearing member and, after a carried paper is caused to temporarily stop by the registration rollers, carrying of the paper recommences with a timing enabling a leading edge of image information visualized on the electrostatic latent bearing member and a leading edge of the paper that has been stopped by the registration rollers to correspond, wherein, at a time of successive printing of multiple sheets, a carrying recommencement timing of an immediately subsequent paper is determined using information of a carrying recommencement timing of an immediately preceding carried paper.
摘要:
A link member interlinks an external member forming part of a cabinet of an apparatus and an internal member capable of pivoting about a pivot shaft located more deeply inside the apparatus than the external member for causing the internal member to pivot in cooperation with the external member pivoting. The link member has a stretchable length and is provided with a resilient biasing member biasing the link member in such a direction as to stretch the length. When the external member is in its closed position, the internal member is positioned to abut a predetermined contact portion by the biasing force of the resilient biasing member. Parts storage shelves are provided in the space defined between the external member and the internal member.
摘要:
A sheet feeding device of an image forming apparatus receives various operations such as an operation to start an image formation and output process (step S101), inhibits opening and closing of a feeding route interlocked with opening and closing of a storage section if the received operation or a process executed based on the operation satisfies a preset predetermined condition (step S103), and then starts the image formation and output process (step S104).
摘要:
An image forming apparatus includes a photoreceptor drum, a developing roller, a registration roller for positioning and conveying the paper and a drive controller for controlling the drive of the registration roller. The registration roller conveys the paper so that its leading end collides with the photoreceptor drum. The drive controller corrects the timing of driving the registration roller based on the detected eccentric variation of the peripheral surface of the photoreceptor drum and the rotational phase. The drive controller may acquire the eccentric variation as external data instead of detecting it.
摘要:
A guide member, which is constituted by an upper paper guide and a lower paper guide that form a paper transport path, is arranged between registration rollers and pre-registration rollers. At least one of the upper paper guide and the lower paper guide is supported swingably during printing operation.
