摘要： An image forming apparatus may include controls for changing a state of a developing roller from a stopped state to a rotating state. The change in state may be used to avoid deterioration of toner and/or a surface of the developing roller. Changes in state may occur at various times including at a timing corresponding to an outside of an image formation area, a timing corresponding to an inside of an image formation area and the like. In one arrangement, a first developing roller may continue to rotate (e.g., during monochrome printing), while one or more other developing rollers are switched between a stopped state and a rotating state. Alternatively or additionally, a roller which is caused to change states may remain stopped between the timing corresponding to a rear end of an image formation area and a timing corresponding to a front end of an immediately subsequent image formation area.

摘要： Left and right frames are formed of a resin containing no glass fibers and bridged together by a tray formed of steel, a chute formed of resin, and underbars formed of steel. Each frame has a box-shape configured of a plate surface and side surfaces formed by bending the edges of plate surface in a common direction perpendicular to the plate surface, thereby preventing the plate surface from bending significantly. When the tray and underbars expand, then the frames bend slightly to absorb the load.

摘要： An image forming device includes an image forming arrangement including a medium passage and motor, and a temperature detecting unit. A supplying control unit allows supply of a recording medium in the medium passage responsive to an image-forming signal, and prevents supply of a recording medium in the passage responsive to a warm-up signal. A warm-up control unit controls the motor to drive, responsive to the warm-up signal, at a first speed if a detected temperature is least a first temperature, and a second speed lower than the first speed if the detected temperature detected is lower than the first temperature. An image forming control unit controls the motor to drive, responsive to the image-forming signal, at a third speed if the detected temperature is at least a second temperature, and a fourth speed lower than the third speed if the detected temperature is lower than the second temperature.

摘要： A low-voltage power source circuit board is provided downstream in relation to the flow of air introduced through an intake hole and exhausted by a power source fan. Heat sinks are provided on the low-voltage power source circuit board on electronic parts that generate a large amount of heat, the plate surfaces of the heat sinks being arranged along the direction of airflow, thereby minimizing their resistance to the airflow. Air including heat generated from these electronic parts is exhausted by the power source fan without the air heating the high-voltage power source circuit board or engine circuit board that are disposed upstream in relation to the direction of airflow.
