Abstract
Official abstract text for this publication.
An image forming apparatus includes a temperature sensor detecting an operating ambient temperature of the polygon motor, and a controller controlling the polygon motor and the paper feed mechanism. If the temperature detected by the temperature sensor is equal to or greater than a preset temperature, the controller controls, before operation for giving a command to start image formation is performed, the polygon motor to rotate; increases, in response to the operation, a rotational speed of the polygon motor up to a rated speed; and controls the paper feed mechanism to start conveying a sheet of paper at a time when a period of time variable depending on the detected temperature has elapsed, the period of time being preset to be shorter as the detected temperature increases, in expectation of a time required for the rotational speed of the polygon motor to reach the rated speed.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus including a polygon motor and a paper feed mechanism, the polygon motor serving to rotate a mirror for deflecting a light beam to expose an image carrier to the light beam, the paper feed mechanism conveying a sheet of paper to a position at which an image developed on the image carrier is transferred, the apparatus comprising: a temperature sensor that detects an operating ambient temperature of the polygon motor; and a controll…
