Image forming apparatus to control supply of even abnormal levels of a transfer voltage, based upon temperature detected

摘要

An image forming apparatus includes an image bearer on which an image is formed; a transfer device to form a transfer portion between the image bearer and the transfer device; a voltage application device to apply a transfer voltage to the transfer device to transfer the image from the image bearer to a transfer target at the transfer portion; an abnormality sensor to detect an abnormal level of the transfer voltage; a temperature sensor to detect an ambient temperature; and a control circuit. The control circuit controls the voltage application device to continue applying the transfer voltage irrespective of whether the abnormality sensor has detected the abnormal level of the transfer voltage when a detection temperature of the temperature sensor is below a predetermined temperature.
