摘要： An image forming apparatus of the invention conveys paper fed by a paper feeding mechanism piece by piece to a paper discharging unit through a paper conveying path. An image forming unit is arranged in a midway portion of this paper conveying path and executes an image forming process for printing an image based on image data on paper being conveyed. A sensor that detects a type of the paper conveyed is arranged on an upstream side with respect to the image forming unit on the paper conveying path. Image forming process conditions for the image forming unit are set in accordance with a detection result of the sensor. When the paper fed to the paper conveying path is paper not detected by the sensor, the image forming process is started awaiting a detection result by the sensor. On the other hand, when the paper is detected by the sensor, the image forming process is started without awaiting paper type detection. Moreover, paper being conveyed is conveyed to the image forming unit, in which the image forming process is started, in synchronization with a printing operation of the image forming unit.

摘要： In a developing device, a developing roller is disposed at a fixed position to oppose an electrostatic latent image-forming surface rotating in one direction, and a submagnet roller is disposed to be parallel to the electrostatic latent image-forming surface, to have an axis perpendicular to the one direction, and to oppose the developed area opposing the developing roller at a downstream side from the developing roller along the one direction. The developing roller supplies a magnetic developing agent by a magnetic force to that portion of an electrostatic latent image which opposes the developing roller and is defined as a developed area to develop the electrostatic latent image in the developed area by the magnetic developing agent. The submagnet roller has a plurality of segments such that different magnetic poles thereof alternately appear along the axis of the submagnet roller to remove unnecessary particles of the magnetic developing agent which are deposited on that portion of the image-forming surface on which the electrostatic latent image has been developed by the developing roller.

摘要： Using an operation panel a user selects group to which a recording medium to be subjected to image formation belongs out of plural groups of recording media classified according to grammages, a classification processing unit sub-classifies the group selected, to which the recording medium belongs, into plural sub-groups of recording media according to a detecting result of the media sensor provided further upstream in a conveying direction of a recording medium than a fixing unit, and a control unit sets, for the recording medium belonging to the group selected, the temperature of the fixing unit to a fixing temperature in a fixing temperature range and controls this fixing temperature according to any one of the sub-groups sub-classified. Consequently, it is possible to perform fixing processing at an optimum temperature according to a type of a recording medium.
