摘要:
A maintenance pattern forming method includes conveying, generating, and forming. The conveying conveys a transfer member on a surface of a conveying member such that there is a spacing area between two adjacent transfer members on the surface of the conveying member. The generating generates a timing signal for at least one of a plurality of colors formed by a color image forming apparatus. The forming forms at least one of a process control pattern, a position adjustment pattern, and a blade curl suppression pattern onto the spacing area based on the timing signal.

In an image forming device, a correction unit corrects image formation operation based on a plurality of correction patterns. A pattern creation unit forms an electrostatic latent image of the correction patterns on a photoconductor and transferring the image to an intermediate transfer body to form the correction patterns thereon. A pattern detecting unit detects the correction patterns formed on the intermediate transfer body. A speed detecting unit detects a movement speed of the correction patterns on the intermediate transfer body are moved. A timing holding unit computes a set value of detection start timing for starting detection of each correction pattern to hold the set value. The correction unit is provided to determine, in advance of correcting image formation operation, a detection start timing based on the movement speed and the set value.

摘要:
A signal is generated which is active only during an interval of taking one pulse of a series of output pulses of said synchronization detecting sensor, but is not active during an interval of taking more than one pulse thereof. Then, synchronization detection pulses are separated from the pulses output by the synchronization detecting sensor for the respective colors by using the thus-generated signal.

An evaporated fuel treatment device is provided to treat evaporated fuel by using a fuel supply cap with a small size while the flowout of fuel can also be suitably prevented. The evaporated fuel treatment device includes a positive pressure adjusting valve which opens when an inner pressure of a fuel tank becomes a predetermined pressure or more, and a spherical rollover valve which closes the positive pressure adjusting valve when the fuel tank is inclined at an angle equal to or larger than a predetermined angle. The positive pressure adjusting valve and the spherical rollover valve are mounted on one cylindrical portion formed on a fuel supply cap.
